Wish I could understand some things that bother Galen

I really wish I understood why Galen stopped liking baths. He hated them from birth and started to like them when I was pregnant with Flint. We got a few great pictures of Galen, Flint, and I in the tub together and then he reverted to hating baths.
Tonight I tried again, but added milk bath (for me) and it bubbled. I wasn't expecting bubbles, but I usually just wash them away quickly, but this was a lot of bubbles. Galen's so very afraid of bubbles. I really don't understand why. It makes me sad cause I love bubbles. Flint didn't enjoy the bath either (but I think that had to do with such a difference in temperature in the water and out of it).

Tonight I gave Galen a few m&m's (one of his favorite snacks) and he sorted them by color before eating them. It was sooo adorable. I took pics.

The past few days, all Galen will eat is cheerios and cheese sticks. He ate some Spanish rice once too, but then wouldn't again. He used to eat a few more things like graham crackers, peanuts, mac and cheese, and would even eat meat a few weeks ago. I really can't figure out why sometimes he'll eat something and other times he won't. There seems to be no rhyme or reason to what he'll eat and when. I know he's healthy and getting enough nutrients from his Boost Chocolate Milk for kids. He's been checked out routinely and is due for a check up in June, but I'd feel better if he'd eat more consistently and better.

The first thing I want to work on with Galen is his speaking. He's clearly able to say certain words and clearly seems to know more than that. He's been trying to say thank you and welcome again (he used to say those around 14 months old and then stopped). If I could get his speech better, then I think we could figure more stuff out just by him communicating better.
Then I'd like to work on eating on plates and in bowls (like he used to!). He really only eats off the floor these days.
I'd also like to work on his eating habits, but that's pretty low on the list compared to other things he needs help with, and I suspect that's actually stuff that will all be worked on together in different therapies.

Mazzu (hubby) will be reading all the info they gave us so we can determine which therapies we'd both like to try on him. I could just choose some, but it needs to be a family effort.
