We are expecting our second in the middle of July. We plan on using a co-sleeping bassinet, then bed-sharing once baby has more head control. We do have a/c, but have an older home which stays rather warm upstairs. Our room averages 75-78 degrees, and a bit cooler when we have the windows open. Let's assume no bedsharing right now, as I have a co-sleeper bassinet, but may change my mind depending on baby's needs.
What should I plan on baby sleeping in? DS was a fall baby, so I just bundled him up in layers (onesie, footie pajamas), then a flannel swaddling blanket. But now I'm worried about baby being too warm instead of too cold. Is just a onesie enough if she'll be swaddled?
