Oh OP, this is such a personal thing. I never felt broody until I wanted DC3.
DC was an unplanned baby when I was 31 (and had been with DH for years!), and I had DC2 2 years later as that is what everyone else in the NCT group was doing.
I found 2 small children, being a SAHM, parents and in laws abroad, very tough.
And then DC2 started reception and I thought - oh! I am not ready for this to be over. And had a miscarriage. And then had dc3 when kids were 6 and 8. And I turned 40 three weeks after dc3 born.
And I really enjoyed this baby and the gap made all the difference. It was like having a first born again, as others at school and so much older, but without the stress and post natal depression for me. But man, she was the worst sleeper of them all, and nearly broke me. I am 47 now and look at babies, and think ‘oh how cute, thank goodness that stage is over’. 😉
In terms of age gap- swings and roundabouts. Sometimes we look at the 13 and 15 year old and think ‘if we stopped here, we’d be free!’. But the 7 year old is a real character, and makes us all laugh so much, and in a way makes the older 2 a lot closer.
Being brutally frank... if you were late 30s, I would say go for it. At your current age, I think I would count my blessings and maybe get my baby fix somewhere else...
Everyone bigs up the young years but I was not a massive fan of the preschool years, and really really enjoy my teenagers more than I can articulate. On a good day. 😉
