Tv help! Toddler question

So I posted before about my son being hosptialized for a blood clotting issue. For about a month while he was recovering all he's been able to do is watch tv and now I think it's turned into a bad habit. He's recovered now and doing good. I'm wondering how much tv is too much. He used to only get 1-2 hours a day and now it's double that! I think it's partially a comfort thing too from when he was in the hospital. Please comment with suggestions!!! How do I break this habit and how much is too much. He's constantly asking for paw patrol. It affects his eating and sleep because he's just always wanting to watch tv !! 👎🏻
