LO is 7 weeks old. We have an ergo with infant insert and a k'tan wrap. So far I can't get her to use either. Once she took a nap in the k'tan, but I can't get her to do it again or even be in either of them at all... as soon as I'm putting her in she starts screaming and if I stop putting her in she stops crying. In general she likes to stretch out and have her legs straight and to 'stand up'. We do swaddle her often during the day and every night and she likes that.

Any advice? Do I just need to wait until she's older?
