Elaine,
I sympathise with you. I think your FIL is home with Chloe and maid whole day so maybe both of them seem to have a good pact or something. Don't mean to bad mouth strangers but this could probably be the case. And since your FIL sees that your maid see to chloe whole day and thinks maid is working very hard, thus his concern on maid's rest ~ or maybe he fears, if maid not well, chloe has to be cared of to him?> =P
Whatever it is, I think you did the right thing. Express your feelings, make it known. FTWM is no joke. Its already tough handling stress at work and after the whole day, you still have to start work at home with bb and what have you. Have a good talk with your husband, preferably when you have cool down and both can talk calmly, reasonably. Let your hubby see how you are suffering. You need rest too, my dear. Put yourself first, sometimes. THat is v important. Once you are happy, chloe will feel the diff and will be a happier girl.
However, try not to shout in front of her ~ bb observe our daily activities. Not advisable to do things like this cos, she would pick up the habit.
=)
