I'm not sure how old your daughter is but this is definitely a stage they go through. Your family dynamic looks different but they all go through it. Typically it's the other parent they suddenly are all about them instead of their primary caregiver. It sucks and it hurts but it actually means You've done your job well, they are so secure in their relationship with you that they are now confident to start forming new ones with other people. It doesn't last they will swing back to you!
No stupid, I would be jealous 😅. But it could just be that your dad and sister are able to spend time playing with her while you have the responsibility of being a parent, so doing all the things required to keep them clean, full, rested, content. That responsibility might be taking her away from having fun thus the response.
🥹😂 I would be feeling the same way, and I’m not looking forward to the day this ever happens 🫶🏼 but deep down i know im his mumma and no one else could compare to that 🤗
