Here's a few games you can play to add teaching and fun to your routine:
Count the Buttons: Sing a song that helps baby to learn numbers like "one little, two little, three little buttons, four little, five little, six little buttons, seven little, eight little, nine little buttons, ten little buttons on your onesie."
Listen? - Hear That?: Ask your baby to listen for the snaps or velcro on their clothes. When you hear it, use your facial expressions and body language to be over-joyed at hearing the sound.
Sing the Alphabet: The old standby of the alphabet song can be used at any time...you can change it up for older toddlers and see if they can find the differences...start with Z and see if they notice. If you know the alphabet in other languages, now is one of the best times to teach them.
How Many Fingers? How many Toes?: Children love to have their fingers and toes counted...count your own as well, they like to see comparisons.
Take advantage of this regularly occuring time to really give your baby or toddler undivided attention. They won't thank you for it, but they will certainly benefit from it!
