Bumps on my 18 month old’ skin

Aw, ganyan din ang nangyari sa aking son around that age, nakita ko agad on his arms and legs kaya nag-alala ako! Kailangan mo talaga i-check with your pediatrician para malaman kung normal lang ito (like keratosis pilaris or heat rash from the heat dito) or if kailangan ng treatment, because at 18 months mahirap i-diagnose ng mama lang from looking, eh.
