Ds who is 5 has recently developed an obsession for wearing a red top everyday and given the chance would sleep in the same red top. He reluctantly agrees to change out of this red top when we leave the house but as soon as we get home he goes straight upstairs and changes into his jeans and this red top again...if it's in the wash he finds another red top to wear. Does anyone know what this means and if your child's does the same??
