Ds has been going to WDw since he was 6mos old, and we have never had a problem anywhere! All restaurants are very accomiating and welcoming of children, and there's usually enough going on to keep their attention. Busy restaurants= busy servers, lot's of other kids and families. Our son aften strikes up conversations with other nearby kids and has a blast. Don't feel like you only can do character dining. Sanaa has a view of the savannah and you can animal watch, ohana over looks the lagoon and magic kingdom, mexico's sit down place has a volcano and a stream and it fun to watch, the french place has Remy come out on some special cart, the Japanese place cooks your food in front of you...that would be fun and different. Whatever you choose, you will have a great time!
