Hi everyone.
I am here almost by accident, as I was looking for something to do with grandparenting and then discovered a world of painful messages on this site re experiences with mothers and MIL's. So, I wanted to redress the balance a little.......
No grandparent is "entitled" to anything (nor come to that, is any parent) Each of us has to earn the right to be trusted and/or respected by our adult children. If we are, then it is a gift. To earn the respect of a d/s-i-l is ten times harder.
My own mother was dreadful (and I did finally walk away ) so needed to work very hard not to repeat parenting patterns and have been paranoid that I might emulate her attitudes to me as a new mother. Well I am now a new grandmother and it is a total joy to watch my DD mother her new son. Why would I want to interfere when I derive such pleasure from just watching her grow into a confident mother? I want to shout from the rooftops that I am proud of her ....that she is doing a great job!
And that is really what I want to say to all those new mums who are suffering interference and dominance issues from their extended families. Trust yourselves!! You too are doing a great job
don't lose faith in yourself if someone in the family tells you to do things differently, just smile sweetly and carry on regardless.
Bestow your trust and respect where it has been earned, and as you grow into motherhood you will gain the confidence to say "my way - or the highway". Just make sure you have prepared to relinquish that stance when you have d/s-i-l's of your own :-) 
In praise of my daughter (and every young mum like her!)
