How long does it takes for your lo to settle down in childcare? What do you do to help ease the situation? TIA!

Mine 1st week was horrendous! Cry n i have to be there for the entire session. 2nd week was slightly beta. I could leave midway wif her crying for awhile n stop. But refuse to participate in activities. 3rd week was OK. Whine at drop offs but everything else was ok. I learned tat they needed time to adapt to new people n environment. I know parents feel heartache whenever they see their kids cry but it will eventually get better!
