Tips for transitioning from 1 to 2

My daughter is 5 and I admit we have spoiled her quite a bit, In a sense where she didn’t do much for herself before like 5 months ago when she started school, when leaving we would zipper her coat for her instead of teach her, put on her shoes sometimes, brush her teeth for her, dress her, etc (she KNOWS how to do all of this stuff, but I guess for time wise since she’s a slow poke we just always did it) but I’ve been weaning away from it and getting her to do things on her own and I haven’t realized how (lazy?) she is lol she sulks about having to do anything for herself some days (which I KNOW is our faults) anyway we will be bringing home her sibling within the next couple weeks and I’m just wondering how I can make her more inclined to do all those herself like most kids her age without her feeling like we are kicking her out of the castle, it’s a 50/50 now whether she does stuff herself or she sulks
