as a SAHM can I answer your fears ???
I'm petrified that they'll hate me because:
a) I'm a working mum
no they won't, you're a mum first and you have a job. it probably won't even cross their minds, they might want to let you know how wonderful your nanny is though
b) I've got a nanny
and how would you work if you didn't? I bet a lot of the other mums at TT work too
c) It was my nanny who was invited and knows everybody else, not me.
it was your child who was invited, you're just the appendage that gets her there
d) DD will play up because I'm not normally with her and I'll look like a rubbish mum (and they'll all tut and say that's what happens when you're too selfish to be a SAHM)
if DD plays up she won't be the only one and any smiles you get will be recognition ones
its not selfish to work, nor is it selfish to be a SAHM, we don't judge as I would hope you wouldn't judge us
e) Everybody else knows each other already
probably only to small talk with though and smile, you might be a fresh new face and if you smile and say hello and ask about their kids it'll be fine
f) We'll have nothing in common because I work
I used to work, I'm female, I'm a mum, my child goes to TT, I have sleepless night, stupid worries, wonderful cute little stories... you'll have more in common than not
HTH
