15 Month Old Sleeping/eating issues...two Questions, Thanks in Advance!

I wouldn't worry too much about the eating. Kids tend to do this stuff in spurts, they'll hardly eat at all and then start eating a whole bunch. Unless she starts losing weight, I would say just wait it out.

As far as the sleeping, my first daughter did this and at about the same time I decided enough was enough. I would put her in her crib and when she woke up I would go in there and soothe her for a minute and then leave. When she freaked out I would let her cry for about ten minutes and then go in there again and lay her back down, maybe rub her tummy for a second, but not say anything, and then leave. Then I waited fifteen minutes and did the same thing and kept doing this spacing it out more and more. It took a little while but after a couple nights of this she got the idea. It is really hard to do and you'll probably feel like a terrible mother but if you ever want to spend alone time with your husband again, you might want to try it. Good luck, and I hope this helps.

Babies triple their birth weight the first year of life, and then as toddlers they taper off and grow much more slowly so don't need as much food.
I found what worked with my little guy is to give smaller portions on smaller plates or bowls. Servings for a toddler are smaller than for an older child or adult, for instance, a 1/2 egg is a serving for a toddler, and they only need 2 servings of protein a day.

SERVINGS FOR TODDLERS:
Milk/Dairy servings:: 16-20 ounces of milk per day.
Whole milk, soy or rice milk are recommended.
Other equivalents: 1/2 -3/4 ounce of cheese = 4 ounces of milk. 1/4 cup of yogurt = 2 ounces of milk.

Fruits & veggies servings: 5 or more per day.
Serving size: 1-2 tablespoons - Pureed, mashed, or cubed.

Grains servings: 3-4 per day.
Serving sizes: 1/2 slice of bread, 1/4 cup of cooked cereal, 1/4 cup of dry cereal. 1/4 cup of pasta, 2-3 saltine crackers, or 1/2 tortilla.

Non-dairy Proteins (meat, fish, beans, eggs):
Servings: 2 per day. Serving sizes: 1/2 egg, 2-3 tablespoons beans (i.e. black, pinto, edamame, etc...), 1 tablespoon peanut butter, or 1 ounce of fish, lean beef, pork or chicken.

So if she ate an egg, a slice of toast, a 1/4 cup of cereal, a little over 1/2 a cup of fruits and/or veggies, (we love baked sweet potato fries) along with 2 cups of milk PER DAY, not per meal, she'd be eating enough.

And, take a look at this article, there's excellent advice on what and how to offer food to get her to eat:

As far as sleeping, your poor husband! You are the parent and need to take control back from her. My guy is in a toddler bed and there is a gate across his door so, yes, he can get up, but he can't get out (and the room is childproofed.) You can stack two since she's a proficient climber, or put a door knob cover on the inside of her's and your door, or lock yours. Also, she no longer needs nursing for sustenance so the last nursing can be at bedtime.

Put up a gate, or use door knob covers so she can't open doors, and if she wakes up go into HER room, leave the lights off, if she asks tell her she can nurse in the morning or whenever the next nursing is, and put her in bed, don't hold her, pat her back, have some white noise like a fan, her room darkened, and a CD of quiet music softly playing. Keep your voice quiet and monotone, tell her "it's time to sleep, everyone's sleeping." If she cries that's OK, she might, and you may have to do this a few times, but once she realizes how things are and that you're consistent she will adapt.

Oh, and while olives have good fats and antioxidants they have too much sodium for anyone so i would only offer a few as a treat once a week or so.

I took one side of the crib railing down and have crib shoved up against our bed, exact same height with no gaps. I did this with my 14 & 11 yr when they were this age, it worked great to transition them into their own space with out the heartache & sleepless nights.
I hope this helps!
My 15 month old son has become a picky eater too, in the past he has always liked every thing we gave him. I have found if I keep introducing the same foods, he does like them some times. Some times they aren't hungry, nursing provides all the nutritional needs & maybe the summer heat takes from their appetites.

For eating, This is normal. My DD is doing the same thing (15 months old too!) and I brought it up at her checkup... the pedi. said it is a common stage, and that 'grazing' is normal at this age. I have found that when I want to get some more variety in my DD's diet, I will sneak in bites of something 'questionable' between bites of something she really likes. (maybe you could give her some olives, then sneak in a piece of broccoli, followed by more olives. lol.)

As for sleeping, I had the same issue there too. I finally got desperate enough for sleep that I stopped letting her nurse every time she woke up. At first, I made her skip every other nursing. I would pull her into bed with me if I couldn't get her back to sleep in her crib, then move her back once she was asleep. She was a very regular nurser, so I had a set time of when her next feeding should be, so if she woke up before her next feeding I would just do it over and over until it was time. I would give her a sip of water if she was really mad. lol. Now I have her down to 2 feedings, and I am cruising there for now. I tried for a while to get down to just one, but that was a NO-GO!! lol. I figure I will give that a little time -I think she may be in a growth spurt, so I'm not pushing it too hard now.

Good Luck!!!

My 16 mnth old is doing the same thing with eating. He used to be a great eater, and then out of the blue started becoming very picky, and eats very few things easily. I think it is all normal. Could be teething, could be at this age they are so busy and would rather play, could be that they are asserting their freedom of choice where they can, who knows. My pediatrician said to average it out over a week and you will/should see it even out. She was right! Some days he eats barely anything, and others he will eat a lot of some things. He is growing and doesnt appear sick, so I dont worry too much. Although I sure do wish he would eat more things again. I do notice that sometimes he refuses things one day and the next he will gobble it up, so keep trying. Or the way the food is presented makes a difference, for example, if there are chunks of blueberrys in his yogurt he spits them out but if I give him a blueberry he will eat it. Weird. My friends son is the same age, and if she cuts up his dinosaur chicken he will not eat it, but if she gives him a whole one, he will take bites off of it. Try new things and see what works, but dont worry too much.

As for the breastfeeding, my pediatrician also said that technically the baby didnt need the feedings at night after 6 months and successfully eating solids (cereal/baby food). I went to 9 months for night feedings and I was tired too. I asked my ped again at the 9 month check up and she said it was ok, and that if I dropped the night feedings, I would most likely see him sleeping through the night soon after. Ya know what, she was right! Thankfully! The first couple nights he was pretty mad, cried a bit, but I held him/rocked him ect, but after a couple nights (I think it was 3 or 4) when he went down at 7p he didnt wake up till 6a. Im not sure if this is the norm or what but it worked for us. Our son also only woke for one feeding at this time, not every 2 hrs. I know a friend of mine weaned the night feedings with a sippy cup of water as the only option, and eventually he too slept thru the night as well. I think her method took a bit longer tho.

Good luck to you!

Wow, we have the identical 15 month olds! Same as all my other babes though, so I'm not sweating it! Soon enough they'll be sleeping and eating just like the older kids.
