Now that the temperature is cooling off, I'm struggling to figure out what to dress my kids in when we are wearing them outside in the Ergos. It seems that our body heat keeps them pretty toasty, but I don't want to under dress them either. We are going to try taking them to a pumpkin festival some evening soon and it's been low 60s during the day, mid-50s by evening. I was contemplating putting them in fleece footie PJs so we don't need to track down dropped socks. But will they need a hat or mittens? Their little arms do hang out of the Ergos now so I feel like they might get cold. Any tips for how you dress your LOs when baby wearing? (They are 4 months btw)
