Yes, you are unreasonable.
The team is dh-wife-baby, not dh-wife-baby-ils.
It is a deadly mistake to assume that your dil will do and behave as you did when you were a dil
Your dil is an adult and she can pick where she stays the night. Maybe she likes her privacy, a hotel with a pool, time on her own with her baby instead of being a guest, etc. It does not matter
Times change. It is not the same society you grew up in.
Now both parents may need to work to make ends meet, for example.
Job security is a joke. Before, a person could stay in his position foe 50 years and retire. Now, changing jobs every 5 years or so is the way to advance
Bottom line, do not expect your son and wife to be the son and wife you were to your ils.
As for the crib, good call on refusing it. That crib is for sure non complaint safety wise.
Maternity leave is now used to recover and raise a baby.
It is not a vacation, or time to host relatives who want to see the baby.
Your dil just went through a major medical event and I hope she is recovering well.
As for her liking you, it is all about personalities.
You both could be great people and not mix well.
For a relationship to flourish, it has to happen organically. If you force it, you may jinx it.
You are doing great. You see them every couple of months. Continue as is and let's see what the future brings.
