You’re not wrong. But all children are different. Ours seems near perfect and we find we can do pretty much all the stuff we used to–at home that is, we are reluctant to take her out to a restaurant and she is still breastfeeding so no babysitter for any longer than about 3 hours.
A friend of ours, by comparison, is having a very very hard time with her little girl. She finds her very difficult to settle so she is up most of the time comforting her. She gets little sleep and has difficulty finding periods of consecutive time where she can have a long phone conversation or watch a TV program in peace.
You may suggest that she should just lock the little one away for an hour and let her scream herself to sleep, but at that age (she’s about 2 months old) it is most important to let the baby learn to trust that when she needs you, you will be there. Not to mention that it is damned near impossible to ignore your own baby’s crying. Someone else’s is not so bad, but listening to your own, particularly when you are new to it, is heart breaking!
Now in the same way that our young babies are quite different, I’m sure older toddlers are quite different as well. Just because one child is easy enough to cope with, doesn’t mean another is. And some parents just cope better than others.
Fessie may have been exagerating, or that really may be what her life is like. If it is like that, the fact that you have coped with a particular group of children, does not suddenly make it easier for Fessie to cope, or negate any of the problems that she may have.
