10 month old back and forth play

Hi guys, I’m a ftm and my son will be 10 mo on the 22nd! He’s always exceeded milestones- he’s been walking since 9 months. And still constantly working on getting better at it- I’m wondering about back and forth play though! I’m not sure he really does a lot of that- what does that look like?? He seems more interested in playing and exploring himself than doing a lot of back and forth play with me. Anyone else?? Personal experience? Let me know! Tia mommas 🤍
