A part time child takes much longer to transition then a full time child .....a full time child usually takes a full 2 weeks and then week 3 should be much better ....does the child still need a morning nap? is the child better in a high chair with some cheerios or crackers and a bit of fruit ? if the child hasnt been with anyone except mom ( and that in its self is ridiculous ....if your putting your kid in group care then socialize them) then maybe the other kids are over whelming and being in the chair up high will make her feel better then get the other kids up for snack and let her explore the playroom by herself ....maybe suggest to take the child fulltime till she is transitioned
