Lots of interesting and mixed comments here, I can only speak from my experience and hope it will help you a little. I had my last child at 45, he was unplanned and my other children were all older - 25 - 16 years. I had so many sleepless nights as to whether or not to keep the baby, I have no issues with termination, but it didn't feel right, though I was so unsure about keeping the baby. I worried about my age and the effect on the child both physically and emotionally (school bullying etc), I worried about my physical and emotional health am quite fit but still you never know and I suffered from PND in the past. My life was just getting easier as DC more or less independent and I was halfway through my MA and hopefully a new career after struggling financially for years. I felt unsure of how my DC would react - last thing 20 somethings and teenagers want to hear is that their mum is pregnant. So in theory there were many negatives surrounding me - I also worried about what other people would say - again I expected bad responses.In the end after counselling and listening to my heart, I decided to go ahead with the pregnancy and hoped all would be ok.
It was - I had a great pregnancy as good as when I had my first when I was 20, no problems. I had all the tests and thank god all were ok. I worked through the pregnancy and coped with stroppy teenagers etc and was fine. I did end uphaving a C section as he was 2 weeks late and as I had a history of placenta previa and began to bleed after a sweep they decided on this which was fine. I was awake and DH saw him come out - huge at 10lbs 10oz- and perfect. My DD was with me straight away afterwards and all other DC camee to see us that evening, it was lovely to be fussed by my DC . They were all fine about it - though some did voice their initial reservations when I announced the pregnancy. Others reactions were also positive, though I'm sure behind my back there were looks of horror! One woman actually said she would of died if she found out she was pregnant which I felt was a bit OTT.
He is 3 in 2 weeks time and absolutely gorgeous - can't believe that 2 oldies like me and DH produced such a beautiful boy. He is bright and happy - all that a toddler should be and there are no signs of any issues with him at all. It is hard to adjust to the lack of freedom I had, and getting used to spending my weekends in parks again is tough when all I sometimes want is to be in costa with a good book, but thats a small price to pay for what we have. I am fitter than before having him as I spend less on bottles of wine and meals out. He has his neice and nephew to play with (5 and 2.5) and goes to nursery a couple of afternoons a week. I agree with others that parenting a teenager at 60 appears daunting, but having done it when in my thirties I know it is hard going at any age and I think it also depends on the DC themselves - some of mine were easier than others all due to their personality I think. It is a gamble and no-one can know for certain how things will pan out - you can only do what feels right to you. My expereince has been a positive one and I consider myself very lucky to have been given another chance at motherhood. I really hope it works out for you and hope that I have given you some positive feedback.
