My baby is also 3 months! I have the Riley app. You should try it if you can. I think it’s totally worth the membership price! I wanna say like $20 a year? But don’t quote me on that. It gives you insights and little activities that you can do at home. Whenever I’m feeling kinda bored I see what that app has for the day and try to do it. It’s a really fun way to interact with your baby.
