I searched for posts on this and found a couple but am interested in updates. Has anyone tried this therapy? We are very interested but struggling with how at odds the approach is with our traditional PT/OT. Ex: Anat is extremely against tummy time and for weeks all Anna's PT and OT did was put her on her tummy. Anat also doesn't want Anna sitting until she can push up to a sit by herself, whereas her PT will put her in a sitting position to work on other things like weight bearing on her arms.
For reference, Anat and our local ABM practitioner agree that Anna hasn't mapped her left side and doesn't have awareness of her lower back. I can see that they're right in the way she rolls from her tummy to her back, entirely led by her chest and using brute force and her stomach muscles to flip the rest of the way over. She does not roll from her back to her tummy. She tries, but only manages to arch her neck and back while her lower half goes stiff.
