Yeah this. I was nearly 50 before my 2 left the nest (had them both at around 29-30... They went to uni at 18 and never came home - (though they do only live 20-25 minutes drive away!) They went together, even though an academic year apart as DD1 had a gap year where she worked, as she couldn't decide whether to go to uni or not. 10 years prior to that when I was 39-40 and they were 10-11, no way would I have considered having another, when my 2 were close to secondary school age.
I know quite a few women who had 1 or 2 kids who were 10-13, and they were 38-43 themselves, and they went and had another child. Biggest regret of their life. They wish they had just stuck with the 1 or 2. The first child(ren) they had at around 28-32 have flown the nest now they are 50-52, and they still have a child aged 9-10 at home, and some years left of all the hassle, school runs, hobby groups, school politics, hassle with school mums, the money kids cost, and the general day to day trials of having school age kids.
Lockdown was a nightmare, they envy other middle aged women whose kids have flown the nest 5-10 years ago, and secretly wish they could turn back the clock - so they would never had had that last child (when their other child(ren) were around 10-12 y.o.)
As pp said it is a mental and logistical nightmare, and tons more expense! Having 2 close together was wonderful but financially it was a killer, especially having 2 at uni together. Like fuck would I be going through that again 10-12 years later! 😬
Anecdata of course, but no way would I have been having more when my youngest was 9-10 or older. @Louxo94 Don't do it. Be happy and content with the 2 children you have. I love my 2 kids and loved them being with me, growing up etc, but having an empty nest, whilst it was a wrench to start with, is utter bliss now.
Having children is wonderful, and they are a blessing, and mine are golden, and I love them so much, but even though they were generally good kids (both girls,) and caused me and their dad very little bother, it was still hard work! Sometimes stressful, exhausting, and tiring (especially when I had a job 3 days a week as well!) I would not voluntarily have put myself through child-rearing again when my 2 were secondary school age. The positives outweighed the negatives, and I am elated to have 2 beautiful, intelligent, successful, funny, kind young women for daughters now, but it was not an easy ride raising them.
