My parents are very involved. For about 6 months they even kept Blaise for me while I was at work three days a week, but it was at my mom's shop and she got too busy to have him there while she was working. For most of Blaise's life we have seen them at least two weekends out of the month, and of course they have kept him during the week occasionally other than the time that they kept him almost every day. Blaise worships the ground "Papa" walks on and the feeling is mutual.
Since Aurora was born my mom has had to close her shop and is now working 3rds. She works almost every weekend, and sleep during the day. So they haven't seen the kids as much as they used to, and it is killing them. My dad is coming over today to keep Blaise while we go to a meeting, and I am taking both kids to their house tomorrow. My mom is going to help me repair some diapers and she doesn't have to work tomorrow night.
DH's parents are not involved. His dad has seen Blaise twice and Aurora once, both visits we went there. The first time he met Blaise he was 16 months old and I say he has seen Aurora, but she was asleep and he was only in our hotel room for less than 5 minutes, never actually touched her. They took a couple of pictures I think. I have never liked DH's dad and wouldn't be upset if he never saw the kids again.
His mom actually came to Blaise's baby shower, and visited once when he was 3 months old. We have taken Blaise up to see her three times since then. She hasn't met Aurora yet. Her daughter graduates high school in June and we are going up there for that, she will meet her then. I actually like his mom, and she does have trouble getting away. She runs an in house day care and her youngest son has downs syndrome.
