Henry has always been a good sleeper-- well okay, definitely not ALWAYS, but since around 6-8 months he's been a reliably good little sleeper. He pretty much never puts up a fight about taking naps or going to bed, but we've noticed in the last week or so that he seems to be fighting bedtime. At first i thought it was because he was having so much fun with his Oma and Opa that he didn't want to miss out by going to bed.
Several nights while they were here he would tell me he didn't want to go to sleep and he wanted to play with Oma and Opa and then agree and seem fine when i said it was time for rest and after he woke up the next day he'd be able to play with them and have lots of fun. A few seconds or minutes later he would completely melt down about something seemingly unrelated, i.e. no snacks in bed! It's almost like he's overtired, but he's going to bed at the same time and waking up later now that the sun is rising later, so i just don't know. The behavior has continued after Oma and Opa left so i think he might be finally entering fully the "another glass of water" phase.
An upshot is that i've been able to put my music classes with Silas to good use. Henry seems to approve/deal with my voice and now i have at least a few more songs in my repertoire.
