Personally if your baby fell off the bed and started having neck spasms 2 weeks later at 7 months old would you get an mri for your baby to be 100% they are okay a mama to another mama?? Yes Iv spoken to a neurologist and she said she doesn’t need one but at the time she asked if my baby is army crawling asymmetry and I said no because she wasn’t at the time and now she is. She is in physical therapy currently as her right side of her neck seems to be a bit weaker then the left side.
