Thank you, Aren, Sherrie, Faith, and Laura, for your quick response.
Aren, yes, she was introduced to this at an early age, and has received only positive reinforcement for using the iPad, through the device itself and her family.
She does not have any attachment issues; Her mom works at a full-time office job, and her father is a subsistence worker (hunting, fishing, trapping, hauling wood and water; repairing ATV and snowmobile). I only visit the family for 90min/week, so I don't know what happens with the family dynamics. The child is friendly and happy to greet visitors. Both parents are involved in the program and interact joyously with their child during home visits, playing games & sharing artistic moments. When I leave materials for the games/crafts for further use during the week, however, I'll be told the next visit that they did not repeat the activities during the week.
Sherrie, I've shared AAP recommendations for screen time for babies and toddlers with the family, and we have discussed this. The parents don't count the minutes/hours their child is on-screen (either watching t.v. or playing with the iPod), but assure me that they're not overdoing it.
I have observed the child on the device only once, when I dropped by the house to leave an invitation. She was totally involved with the iPad and didn't seem to know I was there; she waved bye, at someone else's suggestion, without looking up. She does not use the iPad while I'm there for a home visit, but her parents tell me about how excited and proud they are about how much she can do on it.
Faith, I will invite her to show me her apps in a future home visit. I may be able to take some of the concepts and develop a game or activity that matches the activity in the iPad.
Laura, weakening of fine motor skills is one of my concerns with this child. I'm making activity packs for each of my families during COVID-19 isolation, and will include recipes for making play dough, with suggestions for use. I'll also encourage the parents to participate in fine motor activities (I used to have a fine-motor Olympics with my kindergarten!)
Thank you all for your ideas!
