T.T.
This is normal mine did the same thing. We moved into a new home the day before her birthday. She slept fine and then a month later she would wake up all night long and stay awake! After three day's of this what I did was instead of putting her back down to sleep at 8:30 am when she was tired I kept her awake. I gave her only one nap during the day...making her utterly exausted (as she made me). After two day's of this...she went to bed and stayed there.
Re the eating thing....oh yea been there dont that. We had day's that she would only eat Cheerieos. She does get a daily vitamin in her juice each day.
Then after her sergery she would only eat 2 slices of Turkey breast for two weeks. Since she was loosing weight I did get concerned. I put her on formula for her morning Sippie cup and fed her what she wanted and then would give her more options each day and wait and see if she wanted to eat them.
Now at 18 mo she wont eat breakfast and for lunch only eats the same thing every day for lunch (sliced turkey, diced tomatoes, string mozerella (sp?) cheese and a fruit cup and if she is still hungry gold fish. For dinner she will eat anything. Hey as long as she is eating.
I am told She will do this as she is asserting herself. Also to expect restless nights as she is teething and going through growth spirts.
Good luck I am right there with you!
