Talk to me about a 10 year plus age gap

[SunnyRiverside]

My kids are 11, 14, 18. 18yo no longer lives at home.
I have a partner and we’re planning to marry and he hasn’t any kids and really wants one. My heart says yes, but I’m worried how such a large age gap would work practically. Can anyone with experience talk to me about it? Do the older ones resent a new baby in such a different stage of life?

Considering your 18 year old is 'complicated', your existing children that have dealt with what the 18 year old has done and your age I think another baby is madness.
Are you scared he will leave you if you don't carry his offspring?
I had a friend that had a baby 'for him'. He's now raising another woman's two children with little contact with the now 16 year old child.

My children have a ten year age gap and are really close. At the start there was sibling jealousy but oldest soon got over that. I’m in a two parent household so both children always got one-on-one time/ needs met and dealt with by DH or I. The oldest was never used for childcare either (well, not until they offered in their twenties). Friends of mine have large age gaps with their siblings and are also really close. OP do you feel mentally and physically able to do it all again?
