I am a grandmother and remember when my own daughters were that age. Do you work or are you a stay at home mom? If you work and grandma's taking her for her vacations is the alternative to daycare, then I say let her do so. Better to be with her grandma than at daycare. If you stay home all the time with her, then if grandma taking her away bothers you, by all means argue away to keep her with you if that's what you prefer. She is your daughter; not her's. That said, it is good for your daughter to have this extended family, and I do hear some jealousy in your post. No matter how much grandma has with her, she is still your daughter and your daughter will not grow up confused about that. You will always be number one to your child. But grandmas are important in their lives, too. My own granddaughter has been the center of attention to her other grandmother since birth, and my daughter goes through the same pull and jealousy over that, too, so I do know where you're coming from. The grandma brags on her, by the way, because although she is not her child, she is an extension of her own child (her son, your husband) and to grandmas everywhere, those grandchildren are the apple of the eye, fun to spoil and loved dearly. Be happy she loves her so much. More love can only be good for her. It is hard, though, for you to give that much of her life to this woman, but try to see it from the aspect of what is best for your child. You should have first choice on her time, though, because you are the mother. Also, your husband has rights over her, too, and if he wants her to have some time with grandma, you perhaps can allow that while also putting limits on it. If he is not willing to compromise, shame on him, but you should also do some compromising, as long as she will be safe -- which you said she would. If it were me, I would limit her going so far away so often just because of the fact that she is still so young. And whatever you decide, stick to your guns and put your foot down and insist. Many times through your daughter's life, you'll find you are her best and sometimes only advocate.
