My baby is almost 5 weeks old now, and probably close to 10 lbs. I've been using the Ergo, without the insert, for short periods. He loves it, and usually goes to sleep. I wear it a little high, and froggy his legs in. His head is supported by the back of it, and I don't do much--usually just walking/bouncing him.
I've been concerned about safety and development...so I just got the heart 2 heart insert. I'm debating whether or not to keep it, because I can't seem to get him comfy in there with the insert. When he's fussing, or my toddler needs me, it's easy to just pop him in without the insert.
It's also been hot as heck here and the insert seems like a lot of extra fabric.
Am I wrecking my kid using it without the insert? Anyone have experience with this?
