We have two boys aged 4 and 2. I absolutely loved the age gap between them (2y3m) and would have loved to have had the same gap again, but DH wasn't on board with having a third child until very recently, but he'd prefer to wait another 12 months or so before TTC (and realistically we wouldn't be aiming for a baby to be born in Dec/Jan as DH wouldn't be able to take any time off so would delay even more) for very good reasons, so age gap would be around 4y between DS2 and potential third child assuming it doesn't take us long to conceive (we've not had problems in the past, but you never know). My worry is that the older two will be close in age and play together, have similar interests for days out etc and then the younger one will always feel left out. I know lots of people with 4/5/6 year between their first and second child and they have lovely relationships so it seems, but I don't know anyone who had two relatively close together and then a third child with a bigger gap.
Any insights would be very much appreciated, thank you!
