Preschool IPad Ideas

My girls are starting preschool (homeschool) in January. I bought the Busy Toddler Preschool course, my husband and I are excited to start.

They are both nonverbal (no words except occasional mama, dada, and “I did it” - compliments to Ms. Rachel (they just turned 4) and I was also looking into something on the iPad. They’ve only used an iPad for Speech Blubs, which they enjoy.

I’ve seen ads for ABC Mouse and Hooked on Phonics. What are y’all’s recommendations?

** edit: I forgot to mention, we have an iPad, it is only used for speech blubs and nothing else; once they’ve been on speech blubs about 10-20 minutes we turn off the iPad
