Hello,
I am a bit helpless and need some advice. I live with parents and grand parent in laws. My problem is that my grandfather-in-law makes it a point to criticise me for example I am changing the nappy of my son and he says to the baby "ooo is she manhandling you?" and I try to check the temprature, he says" ooo is she pressing you?"
if baby wets his nappy (he wets them frequently ) "what? has he gone agin?" and if I leave him even for a few secons(when he is around" "ooo has your mother left you and gone" and he laughs.
he asks me questions . He is old, refuses to take his walker but runs and when I ma busy and I sometimes don't notice, my husband asks me to move( normal thing to do) but his expression makes me feel like w orm.. my rand pa -in law taunts me, and I feel bad. I don't have any support from others and I get upset because I don't like him trying to tell bad things about me to my baby.. am I being over sensitive?

Wow. You described a lot of how I act and talk around my grandchildren.
And like your grandpa, I'll bet, it is suppose to be good natured fun, but can be seen differently.

Tell him that even though it is just kidding, it bothers you at times and
Please try to be more considerate.
But grandparents can be obnoxious, I am... and I'm good at it.
So don't expect too much.

He may be over obnoxious... and you may be a little over sensitive .

But take him with a grain of salt and enjoy your baby.

Thank you :) feels better talking to someone. He is little bit deaf and wears a hearing aid, I feel a bit vulnerable telling him so because I feel he won't care and it may get worse. But I will try.

His behavior sounds perfectly normal to me. He's not being mean to you, he's just being "grandpa".
