Family before baby is born!

Zoe
I'm due in three weeks and this weekend we will be finishing of DIY etc. Next weekend I will have finished work and it's a 3 day weekend in the UK. I wanted to spend the weekend with my husband as it may be our last for a while! But my Mum now wants to come the Saturday and my Dad wants us to go out for lunch on the Sunday for my stepmums birthday. They want to see me before the baby is born (I saw my mum yesterday and my dad is coming for dinner next week) I don't like saying no but my husband is upset as he wants to spend time just the 2 of us! I feel so stuck in the middle before little one is even here! Does anyone else have this?
