My 3 week old DD is 7lb 4oz - I've taken her out a couple of times in the ergo with infant insert. She goes to sleep straight away but the problem I have is that her head lolls forward into my chest and I worry about her breathing and stop every few steps to touch her hand/check she's breathing. She's fine when I get her out but if I were more confident about the safetly issue I'd be taking her out in it more/longer distances. She's my second but I didn't use a sling or carrier with DS until he was a bit older.
I've watched videos on youtube and I think I'm doing it right but if anyone has any tips on how to avoid the head-loll thing I'd be very grateful.
