I agree, Holly, I feel that my daughter is similar, I love her sooo much and shes all I have apart from DGD, but if I refuse her or cannot help her I feel she might take the huff and I might not see her or the baby for a long time, she has never done this but I try to keep in her good books in case.
Im trying to teach the baby to know that when I say NO, I mean no, but the other granma says as she doesn't see her very often she wont discipline her so looks like I am going to be the big bad granny.
When you love someone it is so hard to balance kindness with laying yourself open to being used.
