is my child too young?

Just want to get everyone's opinions on this. I haven't started doing it yet today is my first day and feeling a bit worried about it. Is my 2 year old daughter too young to be left unsupervised playing in her bedroom? Please no Nasty comments. I have her up in her room right now watching peppa pig on her bed. I also have the monitor so I can here what's going on. By sounds of it she's got out of bed anyway and doing something eles. All she wants to do all day is have Bing or peppa pig on and there's only so much of all that I can take 😭 so was hoping I'd be able to leave her up there watching it while I get on and do some house work ect. But I don't know if I should be leaving her up there 😕 when did you all let your little ones play in their rooms along? I mean I don't have stair gate on her bedroom door yet so she's got run of all the upstairs atm. I think this is what's making me most worried? Maybe if I put a gate on her door will she be more safe just playing in her own bedroom? And please no horrible comments I am a stay at home mum my partner works full time. She doesn't have her naps anymore so I get no me time! All I need is half hour or so where I can sit and watch my program have a cuppa and do whatever 😔
