With lo 1 I didn't do a whole lot of babywearing, but with a toddler to chase I am definitely going to need to this time! I have a wrap and an ergo, but I don't have the insert for the ergo yet. I like the coziness of the wrap but it's kind of a pain to put on. Is the ergo with insert better? How long do do they need the insert? Baby girl is around 9 lbs now at 3 weeks.
