Ladies Can You Help Me Out On A Decision

I will make this simple, ok im about to have my daughter, im 38 weeks pregnant & its any day right now..my child father and do not speak anymore since we split he hasn’t checked up on baby at all, he the type to let his pride get to him. So he wont even bother.. the question is once i go into labor should i let him know? Or just let him mother know? Mind you all we do have a 3year old son together as well & wasn’t on good terms once i had him but he made it to the hospital asap. I just want to know some of you all opinions & what you all would do ?...
