Ay, nakita ko na yan sa aking daughter din! Those red dots on the feet can be from a few things, sometimes heat rash, sometimes just irritation from the socks or labas labas, o baka nagkasakit lang siya ng mild viral rash na lalabas lang sarili niya, kaya siguro best to have your pedia check it out para sure na wala lang serious, lalo na kung may itch o may other symptoms pa. One of my mum friends' baby had something similar and it cleared up in a week, pero mas peace of mind lang talaga pag na-check ng doctor. Let me know what your pedia says!
