Elly asked to open the new packet of toothpaste we bought today. Then he spent a good 10 minutes practising his hand-eye coordination and fine motor skill (taking the tubes out of the boxes and putting them back in).
It doesn’t have to be toothpaste – and it shouldn’t be if your toddler is likely to open and eat any. Anything that comes in a cardboard box and can be handled easily would do. And there you have a nicely filled in time gap, or a quick few minutes to get something done.
