No hands-on experience - mine goes to daycare full-time all the time, even
when grandparents came to visit us. For my daughter and her friends, when
gandparents were at home, they did not want to go to daycare and cried for a
couple of days when dropped, although they had been in the daycare center
for more than a year.
I'm afraid it will take longer time for your little one to feel comfortable
in the daycare center, if you start with part-time.
