I think I might have ppd

I have a 14 month old and a 3 day old. I’m currently breast feeding our newborn so he will sleep in bed with us. I’m currently feeling bad because I feel like my daughter feels felt out from the cuddles and bonding time. But every time I try to lay with my 14 month old she just cries and wants to be by herself. I’ve cried myself to sleep the few nights because I feel like a shit mom because I’m spending more time with the newborn than her
