Trust me that is a mozzie bite. Your LO has allergic reaction to mozzie bite. My girl has the same problem.. the spot will be red & swells up. There will be like water sac in it. Brought her to a skin specialist when she was younger & yes, it was allergic reaction to mozzie bite. Check your hse or the environment your child is in. Sometimes it just take one bite for it to have multiple spots.
my LO gets this after being bitten by mozzie, I apply mustela cicastela cream until it heals completely - it does take quite some time for the mark to completely go away, but just be patient and keep applying.
My 17mth LO also always have this rashes then will will transform to water bump after 1day. I apply sudocrem and BM
