Bit of an odd question, but my kids are older now and I can't really remember this stage, but basically I am writing some fun board books for 3-4 year olds and wanted to get the grips with some funny and serious behaviour quirks for this age group. Current ones I have are: slurping food, staying in own bed, remembering to say please and thank you, washing your hands, brushing teeth properly. I'm sure there are other delightful little habits and behaviours I've missed. I'd be glad of your help if possible!
