I have two daycare children, a 2 year old dcb and a 19 month dcg. Both suffer from 'Grandma~itis'. Not as bad as the description you gave of your dcb, but frustrating as well!

I always have to deprogram them when they've spent a day or weekend with grandma. The one 19 month old dcg spent a week with her grandmother at the cottage. Boy did I pay for it when she came back. She literally forgot how to self soothe, how to feed herself, how to play alongside other children!!

These Grandparents are not doing their grandchildren any favours.
