My 8 and half old ds just loves being on his feet all the time and is curious to explore everything. However he now seems to have lost interest in his walker which only gets used in kitchen as pile to thick on other carpets and his leapfrog activity centre. Does anyone have any other ideas for good equipment to save me having to walk with him all the time - kills my back!! He is very strong on his legs, but has not yet mastered balance!!! Its even getting to the point where he wont sit and play for very long - jsut wants to be up!!!!
