Still such a crappy sleeper

J is almost 7 months old, and is still such a crappy sleeper. I never held her to sleep, or let her fall asleep to eating. I don’t pick her up every time she cries. Usually I just go into her room and give her back her soother, give comfort, and she goes back to bed. But lately it’s a struggle between 2-5am. I am losing count with how many times I am up. I am starting to feel newborn tired again. It’s making me more frustrated than I should. I know I should ask for more help, but my partner works crazy long hours, and I don’t want to bug him. But then part of me just wants him to take the lead sometimes and help me out. After saying how crazy our sleep has been, why should I even have to ask? Sorry for the rant, been up since virtually 3am and just needed to get it off my chest.
