Congratulations on your news!
DB an i are 21mnth age-gap. I had a very happy, loving childhood but my parents found it taxing at every stage, partly due to the age-gap:
DB wasn’t developed enough to be gentle with me as a baby, and too young to understand what a baby sibling was- he just resented my presence. Multiple stories of him whacking me.
We played together as lot as toddlers/children. It’s an age-gap where they’ll play the same games and can see the same films, do the same holiday activities.
I remember idolising him and having fun, but my parents will tell you that for most of childhood I was furious at DB- hated him being bigger/stronger/doing big boy things, jealous when he got more attention. Teased, scratched, hit, bit him.
Just as we were growing out of all this, high school started- we’re 2 school years apart so 6 years straight of at least one of us doing GCSE/A levels. Extra hard for our parents as we were different types of student who needed different support from them. The year I was in Yr11 and he was in Yr13 was the toughest for everybody. Think DB and I ignored each other a lot then.
We’re in our 30s now and laugh about all of the above. Parents made it through with their sanity and marriage in-tact. DB and I are really close (I still idolise him!). Probably more to do with personalities/shared interests than the age-gap, but it helps to go through similar life stages together
Hope that gives you a realistic view and assurance that it works out OK. Some advice I've picked up from my parents is:
- support is really important, especially in the early years. Mum-and-baby groups were a lifeline in terms of arranging playdates/help.
- Don't tell DC1 they'll have to be a big girl now their sibling has arrived/ they'll have to set an example/ they can look after or protect their sibling. WAY to advanced and too much expectation for DC1 who is still only a baby themself!
- When you talk to DC1 about the baby, instead of "the baby", say "your sibling/bro/sis"- helps them feels connected to it.
