The older ones are at the age where they are excited about learning to read....maybe some books? Also, we love when the kids get things that will get them outside and active. Maybe a lawn game, a scooter, etc. Also, if any of them are girls, hair accessories are always fun.
As for the babies, clothes are always a big help to the parents, as they grow out of clothes so quickly that first year. Or, if you want to think ahead, something they can sit on and push around will be fun for them in a few months.
