E.T.
Dear Elys,
I usually just brows through the messages but yours caught my attention. I am a grandma raising a grandchild (now 5). Second time around I feel I need to be up on the newest and at the same time refer to my resources of experience.
Your child is 8 months old and unable to turn around? That is something you must attend to pronto. Go see your pediatrician. I don't think your little one is just lazy.
Usually they walk at 12 months and certainly start crawling at 8-10 months. Again, to be sure make an appointment with your pediatrician and have the baby checked thouroughly sooner rather than later! Good wishes, EMT
