Thanks for your query.
Well I understand your concern.The red spots u are talking about can be because of atopic dermatitis
.they are generally like red dry skin
,sometimes scaly or red bumps usually comes and goes
Generally more seen in winter season ,there can be a family history of hay fever
For this u have to give bath daily using mild fragnance free soaps .keep skin little damp that is don't dry it completely .then apply good amt of moisturiser/emollient
.dress up baby with soft airy clothes and avoid rapid change in weather,keep baby away from cigarette .
I hope my advice will be helpful for u in case of further issues keep me posted
