I love this thread!! I think somebody ought to write a book that would be the ideal gift for future inlaws/grandmas!!!
All people and situations are so very different that it would be hard to come up with real specifics. But, here would be what I would tell my inlaws, if I could.
1. Your son is now my husband. He is an adult. Therefore, he is not your 'child'. Allow him to separate from you and to live his own life and to make the decisions that are best for HIS family.... which is now Him, His Wife, and child(ren). Remember, you can no longer expect him to do as you wish. He and his wife now have their OWN wishes... Allow him, as an adult, to go about fulfilling these wishes. These most likely will NOT be what your wishes are. How could they be. He is not YOU. Cut the umbilical cord, no matter how painful that may be for you. You MUST do this.
2. Realize that you and your son and his family may have completely different ideals. Your visions and wishes may be of 'Family Holidays' and 'Family Vacations' and 'Girls day out shopping trips' Your son and his family have a busy life with a lot of other demands and their own wishes and visions. If some of these ideals match, GREAT! If not, Get Over It.
3. Realize that there are now new boundaries. Big time boundaries! Build a mental, emotional, and psychological brick wall. Realize that it is entirely inappropriate to cross this wall. It is NOT okay to cross this line and to butt in to any other adult couples personal life. And it is NOT okay to cross this line and to butt into your sons and his wifes/families personal life. It is their life. Respect that. If you do not abide by this psychological brick wall, you will force your son and his wife to have to create REAL walls in order to live their lives and to have their own autonomy and privacy.
4. Your DIL is not, I repeat NOT your daughter. She is not an extension of you and your family. She is an adult with her own way of thinking and her own way of doing things. She did NOT walk into your family to fulfill YOUR ideas. She and her husband(your son) have ideas all of their own. Just because something was always this-and-such-a-way in your family, does not mean that your DIL should be this way. Just because your family has certain 'views' does not mean that she should adopt them. She is an adult, and as such, she does NOT need another 'mother' or 'father'. Respect her as an adult individual, even if you may occasional disagree on some things.
5. NEVER, NEVER, NEVER do or say anything at all that might come between your son and his wife. They are 'as one' now, and you are the outsider. HELLO... this is painful but true... Never make the common mistake of creating the situation where your son is in the position where he has to choose... 'who do I please'. Because, the wife should ALWAYS win this one. If the wife wants a 'private family vacation', without you, then expect that your son and his wife will take a 'private vacation'. It is WAY too easy to fall into a 'I don't like HER' 'HER against US' situation, just because she is now taking your son away from you, or just because you may not like every little thing that she says or does. HELLO, you are NOT going to like every single thing your DIL says or does. Expecting her to meet your wishes and expectations is simply setting up an impossible situation. HELLO, she did not take your son away from you. He is an adult. He loves her and he married her. It is HER that keeps him warm in bed at night. Do not let your feelings ever let you come anywhere between your son and his wife. NEVER, NEVER, NEVER.
6. A word about grandkids.... They are NOT your kids. You have NO right to tell your son and DIL exactly how to raise them. They did not have this precious baby just to raise it for you. It is their child, it is their job, it is THEIR dreams and hopes and aspirations.... Of course it is your grandchild. And you should be able to love this child, and to go to the park, and eat ice-cream... etc. But, always remember. It is NOT your child. You must respect your DIL and sons role as parents. If you want to spend time with your grandchild, you will do your best to abide by THEIR guidelines and THEIR wishes and THEIR limits. If they say, the child must have a nap, or must not have chocolate, whatever... THAT is what goes! Otherwise, if they feel that you are not respecting them as parents and are undermining how they are raising their child, well, you may find out very very quickly that you will have little-to-no time with your grandchild.
7. If you want your DIL to become a part of your 'family', then it is up to YOU to bring her into the family.... That means giving her equal consideration with everyone else. This means going out of your way to make her feel welcome. If you do not expect your son to verbally 'thank' you after you have a family meal together, then do not expect your DIL to have too. Your DIL's feelings and wishes should be given the utmost consideration. Just as your spouse, your son, etc... Do not expect her to become 'family' if she is not free to be herself, feel her feelings, have control of her life with her husband, etc... She is not your sons new 'pet'. You can not expect to train her like you would a new puppy coming into the family! She has to be respected as a full blown adult family member right from the get-go. This is not something that should have to be begged for, or earned.
As you can see, I have Inlaws that have fallen into every common trap and have broken every rule in the book!!!! To bad!!! It is their loss. They do not see much of their grandson, we would never travel together, etc....
