Moms that are working from home, how do you keep your baby entertained?!

Hello all! I am teaching from home and my husband is still going into his job normally m-f. I have meetings all week and if they are scheduled when my son is awake, it’s nearly impossible to focus. He’s into everything, accident prone, and super cranky from teething. I try the pack n play for a little, rotate toys so he’s not bored of them, videos/songs on the tv, and nothing really seems to hold his interest for too long. He wants to climb on everything so I feel like I constantly have to watch him so he does not get super hurt. I feel very lucky that I get to be home with him and I still have a job, but lately it’s been very difficult to get my work done. He used to go to day care full time so he had constant stimulation and other babies/teachers to play with. Now it’s just me and him all the time. Anyone have any helpful tricks or tips that keep your babies entertained? Those of you that are working from home, how’s it going?
