do not underestimate how hard it is looking after a baby. I did, after all, I've brought up 3, and babysat for several others when mine were young. So now my grandson is 12 months and I'm finding it soooooo wearing. Overlooked the fact I'm 40 years older now with a niggling knee. It's full on and brutal.
I offered to look after him 1 day a week while dd goes back to work, then she'd need to pay one less nursery day. Thank goodness she's smarter and wiser than me. "No mum, you can look after him for as long as you want whenever you want but I don't want you to feel obliged or tie your days down".
I often look after him for an hour or three while she gets stuff done - or goes out for coffee at the weekend with a child free friend, or in fact I just visit and play with him and watch and entertain him and it's great and he loves me 😍
All the times I look after him are extra to childcare so dd and sil can take advantage of a bit of free time together.
But thank goodness she was sensible and recognised my limits. Otherwise dd would be one of those posters writing and complaining that mother had promised the earth and was falling short, and how annoying that is. And I'd be one of those grandparents who felt bad about letting her down.
So grandparents to be - beware. It's a doddle when you're 25 or 30. It's 10 times harder when you're 65 or 70. Be warned.
