I agree that it's best to start children full time full days so they learn the routines as quickly as possible. I tried transitioning just a few days a week in the past and it really didn't work out well. But something that I've implemented is to have the new Mom & baby come for visits at least a couple of times for an hour or so the month before the baby starts so they get to know our faces, voices and the activity level in the daycare. Better transitioning is definitely something I've been working on the past few years after having 3 screamers join in a row.
