The weight issue is a bit hinky but according to her and hubby's schedule she can do the 3x a day feeding. She would have to feed early and then let hubby feed before he leaves for work at 2 and then when she comes home she can feed.
I noticed that now Lex will mostly eat all of his dinner at night. The morning he might take a bite of his food but not much otherwise. He tends to ask for water during the day. I guess he doesn't need a much of his dry stuff being as he follows my almost two year old around and hoovers up after him.
