Whenever we visit my Husband's parents. My mom in law always took control of my son. She feed him, napping, etc. It seems like i don't have permission to touch my own son. I know she might missed her grandson but i feel powerless. What should i do?

I was also like you initially :) I live overseas and my mil comes around like every few months and stays for like 6-8 weeks. It used to annoy the crap out of me. But I've grown to be quite fond of her being like that. It seriously gives me a break from my Son, as I work part time and my Husband is working away 2-3 weeks at a time. Enjoy the time, let her look after your baby and go enjoy with your Husband! :)
