I put Lucas down to sleep in his crib for the first time 2 nights ago. He had slept through the night (7 hours) in his bassinet once, so I felt like he was ready for the next step.
No, he doesn't sleep on his boppy at night. But for some reason he really likes it during the day. It probably smells like breastmilk.
So 2 nights ago I swaddled him, nursed him to sleep, and put him in his crib. The first night he slept 6 hours! Last night was only 4, but still better than constantly waking up. Let's hope this continues!
