Your child has probably exhausted you with all of their energy over the past 12 months! At this stage some toddlers may even begin to understand the times when they need to relax and calm down. They may not want to calm down because running around and playing is much more fun and much more exciting! It is good for them to learn how to relax as it allows them to be rejuvenated and ready to play the next day.
Although your child might be great with sharing and taking turns, they might not enjoy being in a large group. They probably enjoy playing with a couple of children (2-3) and at times they may forget about sharing and taking turns, and end up hitting or grabbing at items that they want. They will sometimes resort back to their old ways and try to be the centre of attention, especially if they have a younger sibling who gets most of the attention.
Your child's attention span is growing and they can pay attention for extended amounts of time if it is a topic that interests them. they can also concentrate on a book for longer which makes bedtime stories much more fun! They may even have a favourite story, which they will make you read over and over again. Toddlers love to talk to everyone around them and hopefully they understand that they need to wait their turn before talking as well as not interrupting. You may need to explain to them that they have to wait for conversations to finish before asking questions. Unfortunately patience is not something wisely practised by toddlers!
