My favourites are books that teach about feelings. Many people find it hard to express their feelings, and yet children still need to be taught to recognise feelings in themselves and others. If you find it hard to talk to your child about feelings, using picture books can be a big help. If you can talk to your child about feelings, a picture book can be really helpful to finish off with.
Another favourite of mine, are books that show what life is like in other countries, and what life is like for children there. Talk about what you know about the country that book is about, and reminisce about the places you've been or even the food you've eaten from there. You might want to follow it up with making the food from that country at home, or take your child to a restaurant to experience it. Maybe you have things from that country, like dolls or fabric, trinkets, photos etc. Make it a bit of a learning experience. Put some time aside on the weekend to spend a bit of time doing this.
The world we live in can be a hard place to live in sometimes. We all make mistakes and sometimes that is the best way to learn, but it can be hard. There can be lots of tears and hurt feelings, and apologies. Sometimes extra effort needs to be made to make things better. To help kids through these experiences, picture books help teach these things at their level. Sharing, lying, having manners, making friends, welcoming a new sibling, and being part of a team are just some of the many skills our children learn while growing up. Then we release them into the world when they are 18! Speaking for myself, I hope that I've prepared my children sufficiently by the time they reach that age.
