DayCare and Breastfeeding

To all Bengaluru working moms, thinking of putting baby in daycare once maternity leave over so at 7th Month. Still want to continue breastfeeding and not add formula. Anyone here who does it ? and How does it work , does daycare take frozen breastmilk ? to feed baby? Or you guys suggest introducing formula. ?? Any suggestions are welcome just want to see what kind of options I have..Couldn’t find a proper nanny in my area. Hence the post. I think daycare will be much better and professional also reliable not nanny who can just go away and not come back anytime-they want.
