Returning to work

I'm returning to work in about 8 weeks and I'm nervous. Nervous about a few things but my biggest one is my in laws having my baby more. They're great with her but it feels like a competition as to who she likes most. I know I'm her Mum so we'll always have a special bond but if she is ever grumpy towards me (which I never take to heart - she's a baby!) they lap it up and comment that's she's fallen out with me. It drives me mad! I'm worried that this "competition" they have will be even more in flow when I go back to work. Stupid thing to worry about but it just drives me mad! Anyone else feeling like that?
