I believe as parents we are programmed to feel more guilt towards our children, it's important so we can love and raise our precious creations well. So, although it can be positive, the 'mum guilt' I have experienced in the past and still sometimes do now is RIDICULOUS.
I had gotten to the point where the only days I enjoyed, were the days my children were at nursery. On those days, I'd feel a prickle of dread about having to go and collect them at the end of the day. I'd scramble around on the other days in between, desperately trying to get my mum, my brother, my dad, anyone, to come over, so that I didn't have to be alone with them.
My husband told me the other day that's it's not my personality to get down on the floor and play with her but it suits him (so she wont be so deprived after all!). I think I'm more of a "teacher" than a "player", I really look forward to her reading, painting, cooking with me etc over the coming years.
