I own my own daycare center, it always helps to start looking early and have a few places in mind, see what age groups they have, and if they know if there will be openings. Infants are the hardest age group to take because of the staff to child ratio, the spots fill up quickly. I have moms come when they are still PG and i have people come 2 weeks before they have to return to work. Ask around, I feel like word of mouth is the best advertising for daycare and it doesn't hurt to have someone you can say recommended you.
If you love a place, but the price is high, it never hurts to ask them if there is anything they can work out for you.I have had people ask me, and I have worked with them.
Goodluck! If you ever have any questions I can help with being in the business let me know!
