Little red spotting found on and off on my 5 months old baby's diapers for 3 days. Any idea if it is due to dehydration? Thanks in advance.

Are you latching? If you are maybe you can try to supplement a little bit of formula milk (or express milk) in case it's real dehydration and it becomes a bigger problem - ie child needs to be warded If you're worried about nipple confusion then you can use a syringe to feed
