I don't have my own kids, but my experience with people with kids is that they're often desperate for social interaction, they feel limited in their ability to go out of the house, and they really don't want the extra work from having guests over.

So I try to act accordingly — help cook and tidy up the kitchen afterwards, help bathe the kids and/or put them to bed where appropriate, or just sit on the couch fiddling with my mobile when not interfering is the best course of action. Just slot into their routine and provide an extra pair of hands. For people you're comfortable with, socialising happens around these things just fine.

Maybe because I'm on kid #6, but what is the hard part again? They sleep most the day, giving you an opportunity to sleep and cook.

I remember kid #1, we didn't remember to burp and he was fussy, but after that, its been fine.
