DS has CP and cant sit unaided. He has all the general parafanalia that we use to help him sit - but its all heavy and cant be taken away for weekends or holidays. Its also not practical to wheel his buggy with its dirty wheels into someone's house so he can eat in it. What we really would like is a big booster seat (he has outgrown the toddler booster seats) that we can take away with us. Does anyone have any suggestions. Ideally it should have a full harness and a pommel as he wriggles and slips out of most belts and non pommelled seats!
Have comtemplated making my own but dont need the hassle and havent the energy!
