feeding my 15 month too much?

Kim
My son is a few days shy of 15 months.  I have been giving him, breakfast... AM snack... lunch...PM snack and dinner.  Bkfst: yogurt (4oz) plus 6oz whole milk with some banana or fruit. AM snack: Gerber grabber pouch.  Lunch is usually baby ravioli and 30 min later 6oz milk.  PM snack: little bit of cereal or sometimes nothing.  Dinner is usually what I eat or sometimes the "little meals."    Then he gets 8oz milk before bed. 
He's been at 25.11 lbs for 3.5 months so he's not gaining too much.  But he has a little tummy forming now! I just feel like maybe I need to cut out the snacks? Or lessen lunch and add more veggies?  The milk he needs no matter what.
