I don’t know what to do with my baby

Baby just turned 12 weeks so she’s starting to pay attention and react to things. I just don’t know how to entertain her and I feel like I’m failing her. I was an only child and I’ve never interacted with a baby before her. I never even changed a diaper so this is all very new to me.

I have a bouncy chair, swing, the piano play mat, a couple gyms with the hangy things, and I have a wrap but I’m looking to get a sturdier carrier as she gets bigger.

Also, I’m a super awkward person and pretty introverted, so talking/signing out loud doesn’t come naturally 🤦🏻‍♀️ I just need some ideas or guidance I guess bc I feel like she’s so bored
