Going back to parenting after a 10+ year gap

[NutellaOnCrumpets]

I have a 10 year old son from a previous relationship, I had him at age 18 so only 28 now.
Myself and my DP have always talked about having a baby together, (he has children that are even older than my ds) and i do get broody.
On the the other hand, now that ds is 10 he can entertain himself, is gaining independence, my house is generally tidy and clean, I have decent amounts of me time as ds shares his time between myself and his dad equally.....
I'm a bit apprehensive about going back to the baby days again and everything that it involves!! I felt more up for parenting and being devoted to a tiny person 24/7 when I was 18 than I do now. I feel I have had the selfish/not ready feelings in reverse!

Has anyone had a large age gap between kids and did it work out ok?

Depends how much you want another child. Not a necessity!
I had DD1 when I was 18 and always wanted more children. Life didn't work out like that for a long time however and Dd2 was born when Dd1 was 18! So rather large age gap...
For the most part it has worked out very well. I'm a more confident parent this time round although didn't really have problems of that type before, but looking back things are better now than first time round.
I have met a few people with large age gaps and things are generally good.weird in some ways however, parenting 2 'children' with such different needs, but they still both need you in their own way.
Incidentally I would love another child but so far it's not to be. So in a way I have 2 'only' children! Dd2 is 5 now.
Good luck with your decision.
