K.C.
E.-
It looks like you have gotten some good advice about foods to try.
I also have feeding issues, in that my nine month old refuses to eat foods, except for crackers and yogurt. And by refuses, I mean regurgitates anything else. No bananas, no applesauce, nothing. My son still wakes up to nurse at midnight, sometimes at 4 am, and then at 6:30 am.
My pediatrician, who I do trust, told me NOT to refuse the night feedings because of his limited diet he probably still needs them. My son sleeps in his crib from 8-midnight, and then comes to bed with us. If you wanted to try to transition to a crib, this might be a way to go, get him used to sleeping in the crib at bedtime, and then just take him to bed, (sleep on the floor, whatever) the first time he wakes up. That way you are dealing with the sleep issues while you are still awake, and not the later ones when all you want to do is sleep.
No doubt he will protest at first, usually the first night is bad, the second night is worse, and the third night even worse, but after that if you stick with it, it gets better.
My pediatrician told me not to get frustrated, to just keep offering the foods, and be patient. Right now my son is chubby and healthy. I was looking forward to weaning at year or so, so I wouldn't have to pump, but will deal with that when we get there.
Good luck.
