A good friend of mine had a baby aged 41 after she got married for the second time, she was pushed into it by her dh, she did not want another child but went ahead anyway for him.
What happened?
It was her third child and doing all the baby stuff did not inspire her to say the least. She increasingly relied on farming out her dd to anyone that would have her, as she was just so busy, tired and trying to work (and also did not enjoy playing dolls, kids games or crafts anymore, on more levels than one she was truly past caring about parenthood and she was desperate to have time to herself) She looked/looks fantastic, and the health side of things did not bother her, however as the years went by she became completely disengaged and completely worn out. Not because she didn't love her dd, but because she has nothing else to give, her energy levels were at ground zero.
Her dh although so pushy about having children at first, soon became very busy doing his own thing, and he was old getting old and could not be bothered to run around after a young child. (3 years older than my friend) He wanted to play golf, have lunches and sleeps on Sunday afternoons.
Fast forward to friends' dd turning 15 and it is pretty hellish to say the very least. Dh is totally out of date with life in general, and clashes with his dd, my friend is on her last legs literally and can not keep up. The whole family argue non stop and dd has seriously gone off the rails. Drugs, drinking and boys. My friend simply does not have the strength to discipline her, she has been worn down with three years of teen hell and has been all but given up. She is also looking after all the other adult children that have also had many problems, and a marriage breakdown. All in all she bitterly regrets it. My friend and her second husband have just separated, she is now 56 and heading for retirement in a few years on her own, with no house as there is not enough equity for two separate homes, no money and dd is now her problem. Ex dh it seems has met someone new and shiny and can not be doing with it anymore. My friend predicted this day herself sixteen years ago when she was making her decision, and although she loves her dd with all of her heart without question this is not the life she planned.
Think very very carefully op is all I will say.
