ok guys I have a bit of a dilemma

So we're considering a third baby maybe when our daughter is 2 or so. We have no family here so my mom flew down to stay with us. It was terrible. She kept telling me I was doing things wrong, saying I was a bad parent..our relationship has changed since then. We used to be close. Anyway I had depression until she left then I was fine. I hate that she made my daughters first few weeks suck. Anyway I'm wondering if when the third comes if she should stay with us again or if I should figure something else out. We really have nobody else who can watch the older two while we're in hospital ...
