Do not feel bad at all. I assume the mommies of your DCK's have all gone through it. I went through it earlier this year when i was pregnant and unknowingly suffering from a Molar Pregnancy and preeclampsia. I would literally lay down on the floor of the playroom and watched them play, lunch consisted of canned soup or pasta. i felt awful and tried my best but as long as the kids are safe and healthy . You are doing the best you can and TV can be educational it won't last forever!
