Summer,
my bb also like yr Bb also.Before He 'fire', he will be very quiet and still, and the face will be red, then he will 'put!' He will smile and laugh as if very satisfied esp when I scold him dirty bb while cleaning him.
Babe,
my boy also drools and blow bubbles with mouth but he is 3.5mths old.
anyway is okie.. one of the mummies quoted from PD that Bb hasn;t learn to swallow saliva so that's why they are playing with it.
