So E slept 6 hours again - every time he does that, I feel like having a party. The past few nights have been like this: 6, 6, 5, 6.
His schedule is weird, though - the first shift goes from 9 pm to 3 am. I sleep from about 10 pm to 3 am. For some reason, after that, I'm wired and lie awake during the second shift (3-7 am), even though he is sleeping. I guess I'm a natural insomniac. Then I sleep again through his third shift - 7 am to 10:45 am.
The problem is, during the third shift, I'm too tired to stay awake during his feeding and put him back in the crib, so I sleep with him. I hope this doesn't "undo" his sleep training, making him unable to sleep alone. Then again, it's light out during the third shift, so he probably differentiates it from the first and second shifts, when we keep the whole apartment dark and quiet. D says not to worry about it. He says sleeping alone is a learned skill and now he's learned it and he can't unlearn it.
Another thing about E: he hates CVS. I brought him there yesterday, and sure enough, he started to scream when I was in the self-checkout. I am no longer mortified by public meltdowns, although the greeter (at the front of the store) fled. As soon as E was out of the store, he fell asleep in his stroller and continued to nap for half an hour at the apartment. So I'm pretty sure it's the store. He likes Borders and Buy Buy Baby, though.
