Some of these things are new so we haven't really had a change to talk to DD's pediatrician about everything as a whole (I plan to when we go to our next well baby visit in Nov.). Here's what she's said so far, though:

sleep- either we try CIO (something we're not willing to do) or live with it

solids- it's promising that she'll at least take whole foods (like apples) but she wants to wait and see a bit first before she decides if this is an issue or not

textures, distractability, and sensitivity- forgot to mention at our last appointment, wasn't as bad then but have gotten worse more recently

She was shocked about how early on she had separation anxiety but she chalked that up to DD being very advanced.

It's comforting to hear that I'm not the only one who went through this (although I'm sorry you had to too!). How long did it take your son to grow out of it? Did you find anything that helped?
