Alexzander's colic has started playing up again. For the last 3 or so weeks he has been having bad bad episodes of a night & I can't figure out why. His routine & diet are still the same as always, so there doesn't seem to be any trigger at all. Unless the change in weather has affected him somehow

He has a bottle in dimmed light in his bedroom then straight into bed, he falls asleep within 1/2 an hour. After being in bed for 3hrs he wakes up screaming & screaming. Nothing seems to calm him down, cuddles, nappy change, he even throws his dummy away!! He just scrunches his knees up to his tummy and cries I massage his tummy and so much wind comes out & it helps a bit. Sooo I tried him with Brauers Colic Relief & that seems to help. I've only had to give him the first 2ml dose & it helps him get back to sleep.

Is it a bad thing to use it before he shows the symptoms? Should I wait until he is screaming in the middle of the night before giving it to him? The reason I ask is because for the last 2 nights I have given him his bottle, the colic relief and then put him to bed & surprise surprise he has slept through both nights. It's all natural stuff so I'm not worried about it being a medication issue, I just wonder if it might become a habit & he will need it every night to get to sleep. How do I know when to stop giving it to him if he has it before the symptoms show? Also even though it is all natural is there an issue with it being a medication & it causing damage due to excessive use?

HELP!
