35 weeks & a toddler

Hello, just after a bit of advice if anyone has gone through something similar.

I’m 35 weeks pregnant & I have a 2 year old daughter, she loves being independent & try doing everything for herself, she has always loved getting involved in everything. But for weeks now, maybe 1-2 months it’s like she doesn’t want to know me, she’s become a proper Daddy’s girl & she will go to him for everything, if she’s tired, hurt herself, wants help with anything she goes straight to him & point blank refuses any help from me, won’t even let me change her nappy without kicking out at me.

Is this normal? Is it because she knows I’m heavily pregnant & can’t do much? She used to come to me for everything & it’s really getting me down now that she chooses him every time over me.
