I think she is a 17 year old who is self absorbed. Most teenagers are. It's normal. She just isn't interested in the whole baby thing. It probably isn't personal to you our your baby. Although, it is worth asking what was your relationship like with her before you had the baby? How long have you been involved with her dad? I'd say she has a lot to be jealous of.. she is about to be an adult and probably moving out of the house in the next couple of years, and you are "replacing" her with a new baby. Now, that doesn't mean that she is intentionally snubbing you and the baby. She may just have NO INTEREST in the baby.
I was never big into babies or little kids either. Still am not the "baby lady" at church. I love my own, don't misunderstand, but someone else's I am not usually chomping at the bit to hold. I have teen nieces that LOVE their little baby brother. But they just naturally tend to love little kids. It is their personality. One actually (a junior in high school) is planning to have a career in special education for LD kids.
It doesn't sound like your SD has that personality. And that is fine. Yes, it would be nice for her to jump in and help you, but it isn't HER baby, so unless you ask (nicely) then you shouldn't have expectations. What was she required/expected to do around the house BEFORE the baby was born? Did she spend a lot of time in her room on the phone then? It was probably acceptable to you then. You can't just change your expectations about her behavior overnight because you had a baby. What have you done to foster a relationship with her and the baby? At her age, most teens would see taking care of a baby as a "babysitting job", not as something to do for their own fun/enjoyment. More of a chore. Has she been required to do chores up until now?
