Sept07b2b:Why would your LO wake-up because of houseguests? Are they loud? Can you use a noisemaker? Is it that they keep your LO up later? I'm just trying to figure out why a houseguest would interfere with your LO's sleep. Maybe if you can figure out the correlation, you can fix the underlying problem. As a general matter, having another person staying in your house, shouldn't really impact your LO's sleep unless something else about that houseguest is interfereing with your LO's sleep.
If we have company, DS's sleep get so messed up. He's distracted by the new people, and fights sleep and gets overtired. Plus, if we have to do our sleep time routine somewhere else, it messes him up. And, yes, guests can be loud.
