Being able to understand your baby is important. That way, you can take care of her needs right away. Every baby is different and learning her signals will continue everyday. Watch your baby carefully at different times, in different places and try to figure out a pattern. Watching your baby like this will also help you to see if anything seems wrong - if you are concerned for any reason about your baby's behaviour, call your paediatrician or community clinic.
As your baby grows and changes, so will their signals. However, during the first few months, crying will be your baby's main form of communication.
