If you use the Ergo with infant insert with your young baby, how do keep them warm outside in the winter? I'm going to have to start wearing DD (9 weeks) to do daycare pickups for DS since it is hard to take the stroller to daycare (lots of stairs). However, it is pretty cold so I want to keep her in a snowsuit, but I have problems fitting her in the snowsuit and using the infant insert, she just seems too bulky that way. My coat doesn't really fit around both of us if I keep it open, and I get cold doing that too. I'm not interested in buying a bigger coat for baby wearing. Pics welcome to show me how you baby wear in the cold!
