My name is C. and I am a parent of a "large" boy myself. I am also an Occupational Therapist that works with young children regarding movement, self help skills, etc. Many times with young ones that are bigger, it does just take them a little longer to get mobile and stable. We provide home visits to families through our company, Therapeutic Living Solutions. There are two other resources that I think would be great to check out for you, if nothing else that to provide you with some information and to put your mind at ease. I am not sure if you are living in Missouri or Kansas, but both states have early intervention programs with specialists that are trained in child development. They are free programs that can help answer your questions and evaluate your son so as to help provide answers if there is a problem, as well as reaaurance. They will come to your home to provide information to you. In Kansas you can contact a local school district to find the one in your area. The program is called Tiny K. In Johnson County Kansas it is Tiny K, Infant Toddler Services of Johnson County. There number is ###-###-####. You can also look them up on the web. In Missouri, the program for the entire State is call First Steps. Their number is ###-###-####. You can also look up information for them on the web as well. Both agencies have Physical Therapists, Developmental Therapists, Occupational Therapists as well as Service Coordinators that can assess your son and address your concerns. They can help provide guidence and additional resources, such as great play groups, physicians, etc. We can also be located on the web.
Good luck and let me know if you have any questions. I can be reached either via email at ____@____.com or at ###-###-####.
Happy New Year!
