Ok, so I know it's only one night but we switched him into the pack-n-play last night because we felt he was outgrowing the bassinet. He was still under the maximum weight but he just seemed a little big for it, not to mention when he'd kick his legs the thing would shake. And so now I'm wondering if maybe the pack-n-play feels better for him and that's why he slept better. It doesn't shake as much when he flails around. We'll see how tonight goes, but last night I only had to be a "binkie replacer" about 4 times, if that.
