Size by height, not age
Children grow at different rates, so height is the most reliable guide. An EU size 128 fits a child up to about 128 cm tall, which in the UK is usually labelled 7 to 8 years. If your child is tall for their age, go by height and buy the next EU size up.
US toddler sizes use a T (2T, 3T, 4T). From about age 5 US sizes run as single numbers, and in the teenage years many brands switch to adult XS and S.
