I personally don't do gradual entry for new starters. In my experience the children adapt quicker by being fully immersed in my daycare for full days and every day. They are never going to start to transition properly IMO and IME until the are experiencing the full day. Generally the shorter days of transition are more to apease the parents but of no great benefit to the child. I can honestly say my most difficult children to transition are those that are either part time, which I'm sure most of us will agree is common and/or the child that on the rare occasion I have agreed to start with a week or so of shorter days or less days.
