definately tell mom about it and if you can try to keep track of how often it happens. do you notice any other differences in him? excessive peeing and drinking can be signs of diabetes. I'm uber aware of this now because my granddaughter was diagnosed last June. first signs were wetting the bed (she's 7) and going to the bathroom all the time and started drinking alot. Another sign is lethargy and irritablility although these dont always become noticeable until sugar levels are really high.
