I have an 18-month-old daughter and 6 months ago we moved back to the town where DH's family live (brother, sister, parents). We've been together 16 years so I know them well, and we all get on etc.
Anyway since we've been back, my DD has formed a close attachment to my SIL, her aunt. Every time she is around DD goes straight over to her, only wants to play with her, wants her to bath her, feed her milk, read her books etc. SCREAMS (and I mean like she's being murdered) if anyone takes her off her, including me. The other day she fell over and bumped her head and I tried to pick her up and comfort her but she screamed louder and reached out for SIL, who took her, gave her kisses and cuddles and she stopped crying.
At first I really liked that that they have bonded (DD doesn't really bond with many people, is quite shy around strangers), but it's been going on for months and it's starting to really get to me - I've even been starting to wonder if DD thinks SIL is her mother? I try to make a joke out of it enjoy the fact that I get a break, but it breaks my heart when I can't comfort her, and it's making me want to avoid them which I know is irrational.
AIBU to feel like this? What would you do? Is it a phase? Do I need to just get over myself?
