I agree with Iam, Norah and VS and probably others on previous pages. I have read everything but my connection is dodgy and if I go back a page I might lose it.
It's not about 'having it all'. Women (like men) work for various reasons. Sometimes we have to, sometimes we want to, sometimes we see it as an obligation to society for political/philosphical reasons. Our choices (and that includes not working) have no bearing on whether or how much we love our children. Childcare does not involve 'palming off' our children - it is very difficult to find someone we trust with our children, and let's remember that there are parents who stay at home but are not great at mothering. Their children get no respite from their depression, resentment or whatever, and the children have no positive female role model. My mum was a SAHM, and didn't enjoy it at all. In those days there were no playgroups or nurseries, and we were with her all day every day until we went to school - cared for in the sense of clean and fed, well behaved - we were afraid to be otherwise - well provided for materially, but not played with or with a sense of fun. My mother resented her life and resented us, although she didn't realise it at the time. My mum has said that she thinks she was depressed, and this could well be the case with hindsight, but I had a miserable childhood, and didn't want to pass that on to my children. I have no doubt that I messed up in other ways, though - we all do, however certain we are that we won't.
It goes without saying that not all mothers (working or SAH) fall into good or bad categories. The vast majority of us do our best, however, and knee-jerk reactions to partial information are unkind and of no help to anyone. How can we know whether the mum has bonded with her son, whether she is deliberately going away so she's not with him, whether she is taking advantage of her mother or what is happening. We know that the grandmother looks after him every couple of months when her daughter is away, and that she 'watches him at weekends', which could mean an hour when her daughter goes to the shops or all weekend every weekend. Why the judgement?
