Just left ds who is almost 3 at preschool for his second session. He screamed worse than he did last week. Feeling really sad about it. I have made the decision that I won't hang around, I just hand him over with a happy positive goodbye and leave. Do you think this is the right approach? I worry that if i stay and play he will expect me to always stay and is just delaying the screaming. Have been through this before with my older 2 but that feels such a long time ago.
