I've just started using the Ergo with LO and am wondering about leg position. Right now baby is not yet able to spread his legs so his feet come out the sides. Instead he sort of bends his little legs up behind him. It's sort of like he's kneeling and his feet are bent up behind him. He seems comfy but I just worry it's not good to bend his legs up like that. Anyone else using the Ergo and how do you arrange your LO's legs / feet?
