Childrens clothes are easier to buy online than adult clothes - you don't normally try your childrens clothes on in a shop anyway - especially babies and smaller children. Internet shopping is ideal for kid's clothes. If in doubt about which size to buy you should always buy the size above the one you think you need - if the clothes are too big the child will eventually grow into them.
But incorrect sized shoes could damage childrens feet - so we suggest that your local shoe shop would be better than shopping online for children's shoes.
