Sleeping

Madison

When do/can I transfer baby from swaddle to sleep sack? She’s 2 months old. I’ve tried a sleep sack once but the second she moved her arms she woke up (she still does this). Does the startle reflux go away on its own or do I need to kinda help her to get used to her arms? When we have play time I usually try to move her arms and legs around to get her used to them.
