This is baby #2 for me, she is 6 weeks old and very large. Baby wearing is pretty critical since I have a toddler too. With LO1 I used both a Moby and an Ergo which were great, but this LO pushes against me so hard in either carrier like she is doing a push up or tummy time. She hyperflexes her neck back and won't allow me to move her head forward so I have to hold her head with me hand the whole time I am wearing her. Any suggestions or tips??
