I've just used water to mix with oats so far, and just loaded the spoon for him (he's nearly 7 months) Because he's feeding himself it is very messy and he got through alot of porridge.. Can i use cows milk this young to mix with oats etc? You'd think i'd know my dd's only 2 but i can't remember! I'm bf and i don't express, so doing it by hand to get enough milk out for his breakfast would take forever....
