A.,
I have two older girls and a little boy who is about to be 1 but when he was born my girls felt left out and jealous, so I made it a piont to include them in bath time, feeding, changing diapers, and let them be in charge of stocking his supplies, that made them feel importent.
I also made special time for them when he was sleeping, either reading, drawing or just being silly. But the most important thing I did was give them more hugs and kiss's then ever and telling them they need to help with the baby because he was so little and he needed help becoming a little brother. So far so good, I hope this helps, good luck!!!
