My parents live 2.5 hours away so when we see them it is pretty full on as we are staying with them or them with us - DD would have had more sleepovers with them as my mum comes down, spends the night and then takes her back for a few days before we come up or meet them halfway.

DH's parents live 20 mins away. They don't make much of an effort to come out to our place. MIL works shifts so I never know when she is working - she often wants us to bring DD into work on the weekends but I don't really see the point (if she's busy all she can do is wave - if she's not busy she buys her crap from the snack machine). The times that PIL have had DD they look stuffed after an afternoon (also not a fan that they park her in front of the TV for most of the visit).
