Breastfeeding question

Jasmine

My daughter is going to be a month on Friday the 6th and I’ve been ebf her and also giving her pumped bottles. But when she’s on the breast i see that sometimes during the day she only gets on one breast or sometimes both during the feeding. And at night she goes on both but not for long and cries. Is that normal? I’ve never ebf my other two girls, so idk if that’s normal
