I'm a FTM and started wearing my LO in the Moby when she was a couple of weeks old. Now she's 6 weeks old, and totally fighting the Moby. She tries to hold her head up but isn't strong enough to keep it up for long. When I try to turn her head to tuck it under the shoulder strap part she gets very mad and fussy. She's only comfortable if I support her head with my hand, which kind of defeats the purpose of wearing instead of holding. We also have an Ergo which I haven't tried to use yet. Is she too young for the Ergo (no infant insert)? Any suggestions to make baby wearing easier?
