3.5 week old has been napping in her swing during the day pretty much since we got home, occasionally I've transferred her to her crib.... And she's awake again much sooner than if I left her in the swing. She takes 3-4 daytime naps about 1.5 hrs at a time.... How bad is this? Leave her in the swing since she's sleeping or am I ruining her forever (joking... Sort of) by using the swing so much?
