Thanks for the pictures! Baby looks good, does he/she have a name yet? What a cutie pie.
I introduced Kito to healthy cereal like multigrain cheerios, chex, cooked veggies, small pellets, etc., around this age. You can give him toys to play with and a stick that won't roll so he can start learning to perch too. Kito also liked snuggling with her stuffed toy lamb. She still likes to drink water from my fingers and she is almost 2. If I remember correctly I think I started giving her baths about the time her wings were mostly feathered and her tail and flights started appearing. Someone more experienced can give you better recommendations. Congratulations, it sounds like you are doing a great job so far!
