when we first got cruisers in oct he was a 3F, last week he was a 4 and a half G! we did go in for walkers but they advised cruiser until they are steady on their feet, LO can take a few steps now but she said it better for learning to have cruisers on, our first pair were brown with a buckle and a dinasoar, his new ones are blue and have 2 velcro straps x
