involve them as much as possible to avoid the left out feeling ... they're bound to get jealous but the more they feel that you need them and want their help, makes it a lot better my son felt like such a big helper and when she came he was so protective over her it was the cutest ever. .. he had his moments where he felt like playing with her like a doll lol but we corrected him and showed him the right way ... he's great with her ... I'm curious to see how he's going to react to having twins added lol

a baby doll tech them how to hold it rock it feed it and don't drop it ect it works I did it twice ☺
