Hi
There is a 13.5 month gap between my eldest two. We chose it deliberately because I has such a bad first pregnancy I knew I would panic if I waited too long after! They are now 4 and 5.
Note that we have ds3 now so it cannot be too bad!
The age gap has good and bad sides, tbh. Things are prob a little more difficult for us as ds1 has mild sn, however bed times are a nightmare as if you put them up at the same time they go mad with each other, but they hate to be separated too so getting them up at diffrent times is also virtually impossible. things like starting school / childcare are expensive times for anyone too, but have been more so for us as it just kept coming, IYSWIM.
The good side though is that are so CLOSE! It might not always last, but right now... it's lovely! They share toys, want the same tv programmes, like the same trips. If I want to buy one expensive christmas gift (eg a playhouse) I can, because they will both like it and SHARE! Given that Sam has Aspergers, he is learning o share in a way he simply wouldnt without Stirling.
Would I do it again? Oh yes, happily! They love each other, potty trianed together, have their own language like twins...
Had finance and Sam's sn not been an issue, DS3 would have been followed shortly by ds/dd4
