I've got baby 3 due September, I talk to my 2nd son (2 in June) about baby sister coming and his response has been to hug my belly and say hello baby, with the occasional whack of course 🤷♀️ My least two are only 18 months apart and I just would talk about the baby coming. E.g I might say when we're doing something fun like swimming "oh shall we bring baby sister swimming when she's here and she can see your goggle", sometimes with my three year old I'll ask him shall we tell baby what you did today and my second son is there. They seem to respond enthusiastically when I talk about the new sibling (apart from when o say the name I think we've picked in which case my eldest says he doesn't like that name and wants to call her tree😅). I also never say my baby to them, but "your baby " or "our baby" seems to go down well. All that to say, it'll all be ok and even if there is some jealousy at the begging the bond come. All the best x
I’ll let u know next week , my little girl is 2 in June and am currently 39weeks with her little brother and I haven’t a clue how it’s going to go just yet but my sister recently had a baby and we was with them yesterday she wanted to hold her n wouldn’t let me hold her 😂😂 but she was so gentle with her so hoping she’s the same for when her brother comes
