Big Hugs!!! Gawd, I hate sleep dep.
Bad News First:
If they're hungry, they will wake up at night.
My family is huge. (At 6'1 I'm the shrimp, and we're nearly all full grown by 12-14). Can we say growth spurt, much? My son at six going on seven is pushing 5 feet tall. Add to the fact that we're all athletic, and you can guess that our biggest family expense tends to be at the grocery store. So while my son was a VERY good eater...we've had to do that caloric race to keep up with his needs (tips, tricks, and dirty little secrets to follow). To this day though, if he's in a growth spurt he'll wake up around midnight to 1am needing to eat.
2nd bit o'bad news:
It might be a physical problem (probably isn't). Twisted intestines, as well as a few others problems can cause slow, steady, weight loss in children. So here's my standard advice: Take him to the doctor to rule out any gastro-intestinal or other problems like diabetes or (hyper/hypo...I can never remember which) thyroid or others that cause weight loss & lack of appetite.
Tips, Tricks, & Dirty Little Secrets:
- Hershey's Chocolate Syrup. Yup. Chocolate whole milk. Warmed up (stove, microwave, or espresso machine...whatever is handy...to apx 100-110 degrees). My son went on a milk boycott for awhile. I figured this one out on accident, and it has been a FANTASTIC thing. We wanted him drinking whole milk until he was 5, and we needed extra calories...and presto..."hot" chocolate. Warm chocolate, really. About the same temp as breastmilk. Bingo!
(My son LOVED nursing, and was okay with premixed $$$ Enfamil Lipil...but he hated any kind of "regular" milk <grinning> I think you named the whole gamut we ran until we stumbled on the chocolate milk trick. And we did the bottle thing. For years. What works, works. FYI, WholeFoods 365 store brand whole milk -no rbst,hormones,etc...but not their "complete" organic milk is only about 2 bucks per half gallon...the best milk at the best price we've found)
- Processed food. Obviously NOT for every meal, we usually did one a day (out of a standard of 5 meals) until he was 3-ish. But a can of Campbells Chunky Chicken soup...with the liquid drained off and put in a cup...makes fantastic finger food. Microwave dinners with shredded meats...like Claim Jumper's Salisbury Steak, with mac'n'cheese & broccoli...or Marie Calendars Fettucini Alfredo with Chicken...or Hungry Man BBQ Rib shaped patty things with mashed potatoes. All of these meats cut up with a fork into toddler bite sizes, and can be eaten with a fork or fingers.
- McDonalds. Chicken McNuggest with the deep fried bit pulled off and small fries.
- Having their "own" food & snack drawer & shelf. We assigned a bottom drawer in the kitchen, and a shelf on the door of the refrigerator for our son's snacks & leftovers & drinks. I kept them full, and he could have anything he wanted at any time. Leftovers after mealtime went in easy open containers and he could eat them as he pleased.
- Eating out asian. Real asian, where the idea of kids behaving, is making friends at other tables and inviting them to play under THEIR table, too. Our personal favorites were Dim Sum & Thai. Dim Sum favorites amongst the kids i've known were turnip cake, steamed custard like tofu with shrimp, shu mai, and shrimp balls. Phad Sie Ieu (wide noodles, with sweet soy, egg, veggies, meat)...was the number 1 thai hit. I mention this, because every "picky" or "barely any" eater we've taken with us has SCARFED at these types of restaurants. Don't know whether it's the kid-friendly, or variety of choices, or types of food...but it's always blown my mind.
- Being home at mealtimes. Sooooooo not always possible. If it is though, give it a whirl. Whenever my schedule had me gone in the daytime (consistently, not just for a day or two)...my son was up half the night. Nursing, or eating...and talking with my mum...yup...he'd hardly eaten at all that day. This isn't SUPER common, but i've known many kids who've done this. "Waiting" for mum or dad.
Most of these tricks, probably make us sound terrible. I have to tell you though, for US, they worked. (My hubby is also an Italian Vegitarian/Pescatarian, & although scottish and norweigan I was raised in Japan...so our house is almost the definition of healthy food. Suuuuuper healthy. And our friends would GAPE, if they opened our pantry and found our shrine to Chef Boyardee, Campbels, & Alfredo Sauce. Then turn around and have a heart attack when they looked in our freezer and saw that it was litterally stacked like a library with frozen dinners. But hey...our son ate what we ate...AND he ate food that if I ate it on a regular basis would have me as big as a house. And his ribs STILL always show.
What works, works.
Good Luck
