Hi T., I'm Mom to 3 kids- 12, 5 and 2. I nursed them all, coslept and practice attachment parenting. I also work at home, with my kids, as we are unschoolers as well. Here's my two or three cents with your situation. :)First, your baby sounds like she's restructuring her sleeping patterns, and growing!, and at four months, my kids all (my one smaller child, and my two bigger ones) started eating baby cereal, and baby food, along with the breast milk. Some people and doctor's say it's too early. I say, if your kid is hungry (keeps waking up to eat over and over again), they are hungry for food too! My son started eating cereal at two weeks old! None of my kids EVER slept through the night. You're lucky you got that at all! LOL My two year old still doesn't, and still drinks alot of regular milk or soy milk. I stopped nursing her a little earlier, cause my son wouldn't stop! So I just had to stop both of them, it was too much for me. My two youngest are both very big kids.I'm sorry your husband doesn't want to help, but he really needs to. You need to be sleeping when your daughter sleeps, as much as possible. The best scenario is if your husband could help mostly with your son right now, which will free you up to take care of your daughter. He needs to know that if you can't get more rest and sleep, you will not be able to do anything. Ask him what he would do if yout got sick and couldn't take care of either of your kids. I hope you're taking vitamins, drinking enough water every day, and also, if you can cut back on the hours you're helping your husband and working at home, it would be ideal- atleast for the first year. I know that this is hard, and even though we'd like to be Wonderwomen, we are not. I had to do it too. Actually I do it for like the first 3 years, but have worked more in the last year- but it's hard. Your kids only go through this one time, and they need a Mommy who's not so tired and frustrated she's crying all the time! Trust me, I know. And I personally won't let my kids cry any longer than a few minutes or so. I slept with them on me so many times when they were fussy- OH, and used something so great, we really can't live without it- Hyland's Teething Tablets!!!! It's homeopathic chamomile, and some other homeopathic stuff in it. We all use it. When she is fussy, give her a few of these, and magic... Your daughter may also be starting to cut teeth, and this will wake her up over and over again too. You can get the teething tablets (and you can use them too to help you relax and fall asleep- we all use them all the time) at Walmart, Walgreen's, ebay.... and they taste good, so she will love them! Please get some! I think that covered just about everything. I also have no help- no family here, and my husband works alot too, but helps when he can. If your husband could also schedule in time to give you an hour- a whole hour, just to yourself (close the door, sit or lay down and just relax) every day or every other day, along with helping with your son, you will feel so much better. I also set a few rules for myself after the third one, that I'm not killing myself cleaning (I'm a very neat person), and if my husband didn't like it if I left the dishes or laundry, he could do them! And he would. Things will get easier, but it does take teamwork if possible. Good lucky with everything, and hope I am a help! Blessings... V.
