Although all children develop at their own pace, we expect that by age 2 children should be using some single words and joining some words together, such as "mummy sleep". However it's important to remember that communication is not just about talking. If you're worried about your child's talking, it can be useful to think about how many words your child understands and also consider their play, interaction and attention and listening skills. These are all foundations for talking. If you're concerned then you can get help and advice from your Health Visitor or a Speech and Language therapist.
