My daughter is the same age as your son. PS- I always offer a sippy cup with water or milk (breast) while she eats. She doesn't drink much, but I don't intend to offer a bottle for beverages once she is weaned, so I want her to be able to use it.
Here is our usual schedule...
6:30am nursing (6-8oz??)
10-11am ish - 1/2 jar of something followed by as much milk as she wants (3-4 oz)
3pm - full bottle (6-8oz)
5pm perhaps some puff to keep her busy while I fix dinner!!
6pm dinner - varies - some nights it is a jar of babyfood, but if what we are having is suitable, I give her some of it (or a combo of baby and 'table' food)
8pm- bedtime nursing
I believe a baby at this age's diet should be primarily breastmilk or formula, but I also want my kid to eat what we eat and get used to our choices. Here are some of the things I feed her. I don't use any salt or butter, etc. :
pea-sized cubes of sweet potatoes, bananas, overcooked macaroni, cheese (not as a whole meal), pinches of homemade crepes, bits of scrambled eggs, unsweetened applesauce.
Watch the diapers. I think to check for hydration, it is supposed to be 4-6 wet diapers aday.
Good luck...I hope it helps.
