Baby boy (9 weeks) hates his swing, hates his sleeper, hates the floor during tummy/playtime. Can't put him down at all without him screaming his head off, EXCEPT he will sit chilled in his changing station on the pack n play. Seriously. That's the only place. Since he can't roll over yet, today I sat in the chair next to it and let him lie there kicking. The chilliest he has ever been not in my arms.
