My current two are 17 months apart. I've kept the jealousy at bay by keeping my toddler involved with the pregnancy and by letting him know that his little brother is his baby to take care of, too. Yeah, it sounds a little weird to call MY baby my SON's baby, but it really makes him feel special. He gets to feed the baby and help change him, and now that the baby is starting to want to sit up and play, my son shows him how to play with toys and wants to play with him. I'd definitely suggest keeping your toddlers involved. It works WONders. Also, while baby is young and should be sleeping a lot, your toddlers can still get a LOT of attention. Don't be afraid to put baby down and have a snuggle with your older kiddo.
