Please help. Baby fell off of bed.

I'm going to be completely honest. My son is 2 days shy of being 2 months old. I co-sleep with my son every night since the day he was brought home. Last night, I put my son in his boppy to bed last night. He has slept in it every night since he has been home due to reflux, lots of colick and a tired Mommy. I am a first time single Mom. Well last night, I think he pushed himself over the boppy. My bed is literally 4 inches up from the floor but that isn't the point. He ended up on his stomach. He was there for probably 2 minutes tops. I cried bloody murder and held him so tight. I fed him, changed him and I've been up ever since to keep my eye on him. When he woke up after that, he was hungry so I made him a  4 oz bottle. He was cooing for almost an hour straight so I dumped the bottle. After he was done cooing, I made him a 2 oz bottle and changed his diaper. He ate 1.5 oz of that bottle. I took my Mom to work at 2:30 and got back around 3:15. He got up to eat at 4:30. He ate 2oz and I changed his diaper. 5:00 comes and he's really fussy so I BF him for about 30 minutes. 6:00 came, I made him a bottle and he didn't eat it. It's now 8:00 and he ate 4 oz. I had to kinda made him eat it because I've been so worried. He has been acting normal other than not eating as much as he does and wetting diapers. He usually eats 4 oz ever 2-3 hours. Sometimes not the whole 4 oz .. like 3 oz. I'm terrified. I don't want someone to take my child if something bad were to happen. Please don't bash me please. I'm a FTM and I have no clue if he is alright or what I should do. Please help me.
