My LO is 9 weeks old with decent head/neck control and she loves being worn. I usually put her upright facing me with her legs inside like a little pouch. But she's getting bigger and I see mamas carrying in that position with baby's legs out of the sling, like its supporting her bum. I feel like when I do that, the fabric cuts into her legs behind her knees. Am I doing something wrong? Any tips for other carries for a 9 week old?
