My LO is 2 mo old and naps exclusively in his bouncer, swaddled and thus not buckled in. The bouncing puts him to sleep like magic and I can easily extend his naps with little bounces if need be. He has never rolled over .... Yet. At what point should I stop swaddling him and/or letting him sleep in his bouncer unsupervised/unbuckled in case he rolls over/ out? Or is this just a crazy FTM worry?

We plan to move him to his crib when he's 4 months, bc DH and I will be home on summer break and can deal with sleep loss from any aspect of sleep training ( and yes I'm aware the 4 mo sleep regression might totally f up this plan...)
