I am 42 and expecting my third any day. There is a 10 year age gap between my current youngest and this baby.
The pregnancy has been fine. It is probably harder than my first pregnancy (I was in my 20s!), but easier than my second when I also had a toddler to look after. There have been no medical concerns at all. Once I got myself worked up about a pre-eclampsia scare and the midwives told me I am just not that old in the scheme of things. They tell me I have fewer risk factors than lots of much younger mums.
Nearly everyone asked some variant of "Was it planned?" or the more polite "Were you surprised?" DH was quite good at replying in a way to embarrass the asker, but I was always too polite. That has been annoying, but most people are really delighted to welcome another baby.
Here are what I think will be the positives:
1). My older DC are delighted. I think having a little one around will make their teenage years more sociable. They have been such a great help during pregnancy and it is sweet to watch them mature in this way. My oldest DC is quickly becoming an adolescent. I think this would have made me a bit sad before, but since we have this new baby I feel less sad about them growing out of childhood and feel I am really able to enjoy my older kids. And this turning into a teenager thing is amusing. We are in our 40s, which may make entertaining a toddler harder - but we have two very healthy older kids with excellent knees that will pitch in.
2.)This is not my first baby, first babies are scary. I do not currently have young children to look after while also looking after a newborn. I hope I can just enjoy this newborn like a PFB without worrying that I will break it. I have considerable expertise in parenting now, and can take the long view. Little decisions about using a dummy, sleep training, creche v childminder matter very little in the long run. I think I will worry less.
3.) Money. We have more of it which is helpful. We also have had to buy nothing at all because everyone we know is finished having babies and happily giving us stuff. Although maternity leave is more expensive now because I earn more than I did 10 years ago. As above, I don't think putting the baby in the creche will do any harm at all so hopefully that transition will be less fraught.
- My career. In the past, I let DH off the hook for 50/50 baby parenting because I though I was better at it. Now the DC are older he does do 50/50. I am going to try (fingers crossed) to hold him to his share of of the work.
- My marriage. We communicate better now, and again we have the long view. We know each so well now, and are more gentle with each other. A couple of baby years and the expected hit to intimacy isn't going to derail our relationship.
It is an atypical family decision, but I am optimistic. It isn't that I don't panic and think "what have we done?", but I also think parenting is so much fun and we get to experience those pleasures for much longer now. (Note that I am also experiencing that calm optimism that happens at the very, very end of pregnancy).
