I know a woman who had her dc around the same time I had my 1st. Our mothers are friends.
Just recently Mum has told me about meeting up with her and her Mum at some social event.
This woman spent the entire meeting explaining to my Mum about how busy she is at work, and how little time she gets to spend with her dc. Dc goes to stay with grandparents on Sunday evenings so that they can do the nursery run on Monday mornings (so that she doesn't have to get dc ready as she's getting herself ready for work - grandparents bring the child to nursery every morning also and collect in evening). Apparently (at 2yo) dc has never slept through the night, and she's exhausted. Her husbands mother, once a week, delivers a week's worth of food to her house for the child to eat.
And, since I've now had my 2nd dc, she was asking how we all were, and saying that herself and her dh were thinking about having a 2nd baby.
My point is, although I think she's very lucky having all the help from her family, I just can't help feeling that she isn't actually looking after the child she has, let alone would be able to look after a 2nd!!!
Also (now maybe you think I'm being really mean???) she works full-time - fair enough - and isn't home before dc goes to bed most nights (relies on grandparents again), so doesn't really see dc that much during the week, but at the weekends she continues to make arrangements with friends to meet up and go to the ballet, the opera, the theatre (where she saw my Mum), out for lunch or dinner, and so therefore still doesn't see her dc.
AIBU to wonder why she's planning to have another child when she hardly sees the one she has???
