I have found the AMP hemp inserts to be my solution to all. Put in a 3 layer and you should be set with a child that age. You can later add another 3 layer or a 2 layer when you need even more absorbency. They are rectangular so depending how you fold them they are a large or small. They are hemp so I'll warn you you need to wash them separate from any other diapers you don't send to theservice for 4 washes and dry between each wash (other clothes are fine just not diapers). Then you can use them and wash them with your other diapers but they are pretty worthless until wash 10-12. They finally defluff enough at that point and then become amazing.
