I have a question for you ladies (esp. experienced moms). My 8 week old has very good head and neck control and has seemed to have a very strong neck even at the beginning. She holds her head up on an angled surface (bobby, my chest, but not quiet all the way up flat on the bed. She turns to look at you if you talk to her. Can I turn her face out in the slings- Baby Bjorn? Others? She is so much happier when she can see things (and his limited time staring at my chest in the sling).
I don't use a baby bjorn for various reasons (positioning, etc), but I sometimes turn DD out in a ring sling when she's wide awake and showing good core strength/head control. If she gets fatigued or sleepy, I turn her around to a tummy-to-tummy position.
Baby is seated, not dangling, and has the support of my chest, if that makes sense.
