Playing With Saliva

Yesterday, I went home and found Jaden doing something disgusting. I was talking to mum in the kitchen when i heard dad scolding jaden. So i went to chack out wat my little rascal was doing. He was sitting on dad's lap, facing him, playing with his saliva. Okay, i noe it is very common for babies to be playing with their saliva. But, Jaden was doing in in a very disgusting manner. Instead of his usual "bubble blowing", he was trying to "splatter" his saliva all over his own lips and mouth. I dunno how to describe properly, he was pressing his lips tight together and then try to 'blow' bubble which will den cause saliva to splatter all over. I wonder where he learned this trick from but it was really darn disgusting and i was disgusted.
