Any ideas I can one? DS, 15 months old, falls a lot and hits his head. We are seeing a consultant on Monday to get him checked out as nursery has concerns about this and fear there may be issues with his muscles. In the meantime they want us to get him a helmet to prevent his head banging stuff ( which happens a lot) . I have googled it but the stuff that come up are big/clunky. any suggestion would be massively appreciated.
