Say sorry to my baby

My baby is a mischievous boy,yesterday afternoon he beated my wife and I twice when we were sitting on the sofa and watching TV.
That's not the first time he beated us without reasons, so my wife asked me to kick him out of the house.So i took him out and closed the door.When he realized that he was been banished,he shoutted loudly outside,after one minute or later ，I let him in,and ordered him make a apolgize at once.As he was just a two-years-old baby, we forgave him at once.
We thought that he had been tought and would not do the same thing again,but less 10 minutes later,he took the same mistake again,he beated us without a reason once more.I thought that's was unforgiveable,and wanted to push him out,but he surrendered strong,so I cheated him,I told him I would like to take him to the building hall and had games.He agreed and was happy,he said he should change the shirt first,I refuesd ,and told him it will not lasted for long,it needn't change the shirt.
I pushed him out of the door,and closed the door at once.He suddenly found he was been foolished ,he turned to be very dispaired and cried,then lied down on fhe floor out of the door,I put up my merchy and ignored that,From the cat eye I saw he started to knock the door hardly and cried loudly,10 minutes later he was still crying,and lieing on the floor again.I had a little regreted and open the door,he was crying with full tears on his face,It seemed like he was deeply heart broken.I asked him to say sorry,he didn't not.
But that time,I thought I should say sorry to him,for 2 years old boy,I was too serious,and I should not cheat him.I should pinpointed his mistake at noce,not only punished him.Maybe he will not trust me again,and thinks I am a cheater.

I started to correct this, but it submitted immediately without letting me edit. Second try:

An apology to my baby

My baby is a mischievous boy. Yesterday afternoon he beated hit my wife and I twice when we were sitting on the sofa and watching TV. (Beating someone is much more severe than hitting someone and implies serious injuries.)
That wasn't the first time he had hit us without for no reason, so my wife asked me to kick him out of the house take him outside(Kicking someone out implies you won't let them live with you anymore). So I took him outside and closed the door. When he realized that he had been banished, he shouted loudly outside. After a minute or two, I let him in and ordered him to make an apology at once (or ordered him to apologize). As he was just a two-year-old baby, we forgave him at once.
We thought that he had been taught(or we thought that he had learned) and would not do the same thing again, but less 10 minutes later he took made the same mistake again; he hit us without a reason once more. I thought that was unforgiveable and wanted to push him out, but he surrendered strong wouldn't surrender easily ,so I lied to him and I told him I would like to take him to the building hall and had to play games. He agreed and was happy and he said he should change his shirt first. I refused and told him it would not last for long and he needn't change his shirt.
I pushed him out of the door and closed the door at once. He suddenly found realized he had been fooled and he turned to be became very disappointed/upset and cried and then lay down on the floor outside of the door. I put up my merchy suppressed my urge to be merciful and ignored that him. From the cat eye keyhole/peephole(I'm not sure what you mean) I saw him start to knock hard on the door hardly and cry loudly. Ten minutes later he was still crying and lying on the floor again. I felt a little regret and opened the door. He was crying with full tears on running down his face. It seemed like he was deeply heart-broken. I asked him to say he was sorry, but he did not.
But that time I thought I should say I was sorry to him; For a  two-year-old boy, I had been too serious, and I should not have lied to him. I should have pinpointed his mistake at once, not just punished him. Maybe he will not trust me again, and thinks I am a liar.
