Parents of kids 2ish yrs apart...

For those mommas who had a toddler who was super attached to them as the only child then had a sibling come along how long until your toddler got more ok with it. My daughter is my best little friend. We have been one on one bffs since day 1 and now since baby she won't sit with me, talk with me, let me comfort her when she gets hurt. Wont give me hugs/kisses/cuddles. Tells me she doesn't love me or she wants me gone. I am devastated honestly. I was her person from day 1. If she fell or was upset it was cuddles with mom. Every boo boo could be fixed with a mom kiss. She wanted to be in my lap giving kisses or holding my hand all the time. I expected her to be jealous and take awhile to adjust to baby brother but didn't expect her to just act like I don't exist. I take her places just us. I try to give her as much special us time as I can but she doesn't want me right now. Anyone else go through this and if so how long until your 1st baby became themselves again. I miss her so much even though she is in the room with me. I love my son and don't regret having him but crying over my relationship with my daughter is heart breaking. I miss my sweet little shadow and don't know what to do. I want my baby back.
