Girls, hi! My little girl is 1 year and 9 months old. We've been going to kindergarten for two months now. Her behavior has changed, she cries at every step. Appetite is low. She wants to be with me everywhere and all the time. If I go into another room, she cries. I'm curious, is it like this for everyone at this age? Sometimes my nerves can't take it anymore. Share your experience at this stage, thanks
