Have you tried any baster or pipette activities with your toddler? Many toddlers enjoy water play so this is a lovely way to allow them to experiment with water while developing coordination, strength and a few fine and gross motor skills. These types of activities provide an opportunity for the refinement of movement, repetition and concentration.
Pictured above and below, Otto finds the baster easiest to use. He enjoying squirting the water in and out of the baster and making bubbles.
At 19 months Otto is really experimenting, he isn't doing a lot of transferring work. You can see there is a little spillage but it's manageable.
I have tried Otto with the clear type pipettes before but they are still too small. He is using a whole hand grasp with the pipette rather than using the pincer. But we've found this pictured (purple bulb) pipette from the Learning Resources Science Kit really useful. The bulb part is super squishing and soft and easy for Otto to use. He mostly uses it with two hands but will try with one hand. For the young toddler, there is so much going on here, strength and coordination. They are also learning how exactly the pipette works and how to suck up and release the water.
If you aren't ready to present these on a practical life tray these are also fantastic activities for the water table, while the child is working in the kitchen sink or even in the bath!
