Stay away,
Sorry but I'm really not getting where you are coming from.
I've never said that, all I've said is that the phrase is meaningless, because
A), I think we're all mums all of the time, so we're all full time mums,
And B) even if you do care for your child 100% of the time, sooner or later, you are going to end up being away from them (whether its cause they're at pre/school, you're at the gym, or you're at work)- will this make you a part time mum? In my opinion, obviously not, which goes to show how silly the phrase is.
The point about me working, just goes to illustrate that once a child is at school, there is no difference between a parent who works, and one that does not - we're all there for our children all of the time, and many women still call themselves 'full time mums' even when they're children are at school, which again shows how silly the phrase is. The only response to that would be for me to say "well I'm a full time mum who also works part time" which in my view is just as mad because parenting is not a competition and it's not about one upmanship.
Therefore, because I think you can't be anything less than a full time mum, and the not very nice implications of using the term, the phrase in my view is meaningless.
