Coin in E's mouth

VERY VERY VERY angry n fustrated today.
I put Ember to play in bb cot while I went kitchen to take porridge. Went back to the room put her into bbchair n proceed to feed her.
She did made the gag face 1-2 times which I find very weird cos I'm feeding pumpkim in porridge ma all mashy n I gave her small mouth only.
Then she suddenly spit out a $1 coin. I was so SHOCKED!!! N at the same time very angry. Becos I was scolding D jus before I put Ember into cot abt leaving his coins on the bed. (He was playing with the $1 coin on our bed.) I really really didn't know what to think n do man. So of cos screamed at D.

But then again it is my fault as I should have made sure long ago that D doesn't play with coins. Its not the 1st time he does n not the 1st time E puts the coins into her mouth already.
N not that I'm pushing the blame but where does D gets his coins????? Who else would give him coins!!!!

N so hubby also kanna from me cos I was really furious jus now.
So I jus added on to the list:
1) NO COINS
2) NO VITAMINS
3) DO NOT BRING THEM INTO ROOM IF THERE IS SMOKE
4) NO SCOLDING WHEN I HAVE ALREADY SCOLDED (doesn't need to be scolded twice for doing something once right?)

But I'm very sure it will only last as long as 1 week before I have to get furious again. Oh n I mean my hubby not the son.
