Your toddler is 4 years and 5 months old!
Your child can probably name and identify between four and six colours and may enjoy a game of pointing out different objects and telling you the colours. Your child probably has a favourite colour that they can identify and will probably want to wear it more often. They will enjoy exploring more of the world and may be pretty proficient climbers. In the park when they are climbing on climbing frames, it will be difficult for you as a parent to resist the urge to help them as they climb higher and higher. It's good to let them climb and have a sense of adventure but just make sure you are near by in case they get stuck.
It’s not very surprising that your child still enjoys playing pretend. They will continue to enjoy playing pretend for a while yet and it helps them to put an order to the world around them. You'll notice them playing games where they pretend to be grown-ups; doctors, schools and mummies and daddies seem to be very popular! When they play they probably get really energetic and excited and will be noisy.
This is normal, but you may need to remind your child that when you are in a cafe or a restaurant or playing at other children's houses, they need to quieten down a bit! Your child is probably becoming very curious about the differences between males and females. This is normal, as a parent you will probably have to sit down and talk to them about some of the differences. They are still too young to understand much, so answer the questions they ask but keep your answers brief! If you are struggling there are many books for toddlers which explain the facts of life for little ones.
Your child is becoming more and more verbal. They will probably be able to talk very well on the phone, so if their grandparents live far away, arrange phone calls so they can talk to with their grandchild. They will enjoy telling stories (especially fictional stories) as well as listening to long stories. When they listen to the long stories, they might mix up some of the facts and not get everything correct, but they really enjoy the attention and the details. Your child is very into itself and will probably brag and compliment everything that they do. They will probably also start calling people names and telling on others. The boasting and the calling names may not be very attractive qualities, but as a parent you will just need to be patient and tell them that calling names is not nice. They will grow out of the phase if you are consistent with your response as a parent.
