I'm very new to baby-wearing, only having used a BB with DS1 (and not for long, because it killed my back!).
I'm starting with a Kari Me for DS2 (5 wks). We're in the South Midlands, weather is nippy but not too cold - 5, 6 degrees? I'm always worried about DS2 getting overheated in the sling, as he's under three tight layers of cotton jersey. Basically, I'm putting him into the sling (his legs stay inside, he's not in a straddle position yet) dressed in a standard babygro and a woollen handknit cardigan. Is that ok?? I read that as long as his head's covered by one side of the sling, he shouldn't wear a hat. He goes into the carseat in a pair of over-sized, snuggly knitted trousers (we have a lot of handknits from my mum!) but they seem way too hot to wear in a sling.
I know he should be wearing less than if he were in the Baby Bjorn, but how much less?
I'm worried about overheating but might have gone too far in the other direction!
