We have recently started taking DS out for errands, etc. I've been using the ergo with the infant insert and have been loving the hands free aspect of wearing him. Here's the problem: starting this week, it has been HOT here and the ergo ergo seems like too much insulation for him in this weather, I don't want him to overheat. I would love to hear what you all are doing wit your LO's when you are out and about. I need another option until he is able to use the ergo without the insert. Thanks!
