dd2 (2.2) started preschool four weeks ago. she only goes 2 mornings a week and i started her for her benefit so she could get some social interaction with other children since dd1 started school in september. she was fine the first week and i was really happy but since then she SCREAMS every time i drop her off. instead of getting better this is getting increasingly worse and she screams as we are approaching the building now. this morning she arched herself and was so tense i couldn't even get her coat off. she stops soon after i leave and i'm told she has a great time there. she is still young and i'm not working at the moment so i don't have to put her through this distress twice a week. what would you do? take her out and leave it for a few months or persevere? please advise!
