My 6 year old is going through a difficult stage at the minute. She seems to be worrying about everything. She has been learning about people who help us and the school seems to be discussing fire and how the fire brigade can help us. She has been waking me up at unusual times eg 2.30 AM and asking if the smoke alarms are working. She was very anxious about sports day and a lot of other things too. Is she normal or should I be worrying too!! Any advice?
