Brain games

What is everyone doing for learning time? He doesn't have a tablet and doesn't get our phones. I will play the tv but he's not intrested in it. He does the shape sorting, the stacking rings and cups. He loves to read so I point out the ABC's and different colors, animals and things. At his next appointment I'll ask where he's supposed to be but I'm a FTM and SAHM so I sometimes feel like I'm missing things. Also what is your opinion on screen time? He has a friend the same age and she always has her tablet so she's so advanced on it and he doesn't even know how to use one. We're not against tablets and stuff but we just didn't think he needed one this early. Thank you in advance. (The books don't teach this stuff😂)
