I've read some people roll a small receiving blanket and place it on the bottom of the ergo to help support their LO until they are big enough to not need the insert.

Yep, I had a "certified babywearing consultant" (yeah, that's a real thing...) tell me you could use a rolled up blanket--use it like a seat and have baby's legs go on either side of it. Then place baby in the Ergo like normal. If you need more head support, you can also roll a small blanket behind their neck.

When my lo was little I used the feet tucked for a long time. You can look at the insert or online for positioning info.

Yep blanket! Like Jess i used the blanket to give her bum a boost. So glad I didn't bother with the insert.

@MrsBrewer: Try lifting her higher. Put you hand under the carrier (on the outside), lift until it feels comfortable and then tighten it more. If I remember right, the waistband should be at your bellybutton. That might help the armpit digging.
