Weird emotions about visitors

This is kind of a mix between a nicu question and a general post partum question. I had a 25+5 weeker two weeks ago. He’s doing well generally, the usual micro premie stuff sometimes but overall good. We visit everyday in the morning/afternoon time to do milk drop off, hold him, talk to drs/nurses all the good things. It has been so hard, way harder than I thought, I haven’t even processed what actually happened. Our hospital allows 4 visitors on a visitor list but only two can be at the bedside at a time. My mother in law texts me everyday when we’re at the hospital to tell her when we’re leaving so she can go. I appreciate that she wants to go everyday but I feel a little weird about it because she truly doesn’t care about me or my husband, only the baby at this point. Does no one care about the parents anymore once babies are born? Is it normal for her to go everyday? Without us haha. I just feel strange that the only time I ever hear from her now is asking when we’re leaving. As a side note, this is her second grand kid but the first she has almost no relationship with because of a divorce between my husband and his ex wife, so this is basically a redemption baby for her that she can actually be with.
