When I had my first baby, 46 years ago, my mother in law visited me in hospital and the first thing she did was uncover the baby’s feet to see if she had all her toes! Didn’t ask, just did it. We visited in laws not long after the birth and mil, without asking, picked up baby and took her into the garden to show next door neighbour, over the fence, MY new baby. I was furious, if she’d asked I have said yes but she didn’t, thought it was her right as it was her grandchild. Couldn’t understand me making a fuss. Because if this I kept her at arms length. I learnt from her mistakes and made sure I didn’t push the wrong buttons with my dil, whom I’m close to. Please don’t be jealous, it’s not worth it, your grandchildren will love you just the same as maternal grandparents. That’s all that matters the love of your grandchildren and not getting one over on the other grandparents, just enjoy them. Plus respect the parents wishes and you’ll be respected too.
