Mya has just started at a Montessori daycare centre today. I agree with nickel where shes says "do the staff make u feel welcome". It makes such a big difference to me if they take the time to show u around,learn ur name & ur childs.
Also ask questions, i had a list of things i wanted to know, especially because it is a montessori daycare, & there philosophy is a bit different to normal daycare.
Make sure u check a few centres out aswell.

As for family daycare, i can't realyy help u there. I dont know much about it. I have heard good & bad stories.

Just do ur research on both b4 making a decision.
I hope u find something that is right for u
