My son has been going to playgroup three days a week allday for a while now,I wanted him to get used to not always me being there as he starts school September plus he has a sister and I wanted to spend some time with her, the problem is he as never cried before when I left him he has also started to go to school for one and a half days a week , I have to stay with him at the school which he is not used to , I feel it is making him regress, when I take him back to playgroup he cries and it breaks my heart, my son is not 4 till August. any ideas please,thanks.
