Had all 4 of mine by 28. DH wants another & I'm not sure... we have 4 teenagers who basically do their own thing. I don't have to supervise them all the time & they feed themselves & sleep well!!! As others have said, the thing that really puts me off is having to be responsible for another child until I'm 60, since I'm now 41. I think I would like some child-free years!
Easy, I've got no energy at all. It seems to have been since turning 40 that I really feel old.. can't sit on the floor like I used to, or stand for long periods... & I'm not pregnant! (although I do manage to do a weekly ballet class)
