36 days old baby is passing stools frequently. Is this normal?

Hello doctor,

My baby is 36 days old. He is passing stool very frequently like 15 times with little or more motion but not very heavy in the last 48 hours. The stool was curdy yellowish color, not like runny or watery, no greenish, no blood, no bubbles. He had the same issue when he was 18 days old, and in between, he was healthy but again he kept going motion and redness spotted in anus area with small spots of skin peel.

Baby sleeps well, does not cry, passes urine usually in a good number of times, and only mother breastfeeding every two hours. Please request your advice on how to stop this frequent motion and reason for this happening and is this normal? He also makes a noise like sounding from inside especially more during night time, having trouble while breathing due to a chest cold, so am giving Rinoclear saline drops three to six hours once depending on his nose block. Please advise why baby makes such noise, is it normal?

I was feeding breast milk via bottle for four to five days when he was two weeks old since he was unable to suck through mother's nipple. I stopped bottle when I encountered this frequent motion and with my doctor's advice.
