Day care in Bergen

Hey guys! I am recently pregnant, due dec 20 and we are moving to Bergen county in the summer. I am going to need a day care for three months after around late March 2024. My question is, how far in advance do you need to get a place at a daycare. What is the process? I know I am far away but I have just always heard it’s really had to get a spot at a good/affordable day care and you should be on a wait list!
