DS is 4 and has grown out of all his 4 year old jeans. He's very skinny and needs an adjustable waist as well as slender legs. I prefer straight or bootcut jeans to skinny ones on him as skinny ones would just acentuate his skinniness. The Next jeans are too wide in the leg in age 5, tough were fine in age 4 size; the Gap ones are not too bad, but more than I really want to pay (and won't fit DS2 in the future as he is as chunky as DS1 is skinny!) Debenhams blue zoo ones appear not to have an adjustable waist and M&S were too wide. Any more ideas please?
