I think there are definite bonuses to being an older mum (though I’m not one!)
I know this is a different gap but here is my anecdata...I had my first at 17(!) and sat my AS levels weeks after (and got 4 As thankyouverymuch).
I’ve just had my second at 29 and physically it was much, much harder recovery. With my first I was shopping and walking miles with a 2 day old and this one I didn’t leave the house for about a week and then I struggled. Both similar births. Also with number one my boobs looked exactly the same before and after pregnancy and birth whereas this one has knackered them! Physically I’d say I was much closer to prime baby producing age as a teen.
Vanity aside, I’m much more chilled now, confident, financially secure and with a good support system.
If I had planned this baby I’d probably have kicked the can down the road until late thirties or early forties. I think for most of us 27-35 is where your career starts to gain some momentum. I’d only last year secured my first senior role and I feel a bit cut down in my prime.
I’m knackered now compared to younger me, and maybe I’d be more knackered in 7 years time, but I think how tired you feel is pretty inconsequential compared to all the other factors at play. I’d rather be tired than struggle financially, not have a career to go back to or be unsure of myself.
