We visit Dp's family twice a week as we are in a support bubble with them. Our DD is 8 months old and is generally a happy baby. Dp's family love her, so she is very lucky to have family that care about her.
When we get there Dp's mum and sister usually take it in turns cuddling/playing with DD. If she gets fussy or starts reaching for me then dp's mum will always pass the baby back to me. But his sister will either try and walk away from with DD or try to settle her, sometimes till the point that she's really upset and then I'll step in and take her. She will avoid passing DD back to me at all costs or on the rare moment that I have DD in my arms, Dp's sister will walk over and put her arms out to try and get DD to reach for her. Or if I'm trying to settle DD she will walk over and ask if I 'want her to try'. I honestly don't have this problem with my own family, if DD is unhappy then they'll pass her back to me.
I get on well with dp's sister on the whole but I know when I take DD back she's not happy, I understand she's excited to be an auntie and I love that my child is loved but it's becoming too much at times. It feels like she's not happy to see me hold my child, she will physically come and take her from my arms at times without asking She is a fair bit younger than me if it makes any difference, she is 19. She makes comments about them taking DD overnight and I'm not even at the point where I am considering leaving her overnight with anyone.
So how do I politely get her to back off a little.
I don't want any confrontation, I just want to be a little more assertive.
If I speak to DP he will speak to his sister if I asked him to, but she would get really upset by it and that's not my aim at all.
Help please!
