Defecation 4-5 times a day in a child at 1 year old with an allergy to milk protein

Good day. Tell me, please: my son is 1 year old, breastfeeding is over at 3 months, at the moment the child eats everything except dairy products in any form, because he has severe milk protein allergies. New products are introduced gradually, very responsive and can pour. Recently, I tried to give bread (both black and white), my son really liked it, but sprinkles it, so I make bread and cookies on my own. I often give him oatmeal cookies, no allergies, but recently noticed that walking to the toilet can be 4-5 times a day, while the stool is not liquid, not green, and the child feels good. The same situation happens with bread (on yeast). Also, the child basically loves to eat and we eat about 300g. Tell me, is this the norm with such a diet, is it the quantity of crap or not? We eat vegetables and meat (fish) mainly, i.e. a lot of fiber. Oatmeal is also removed in the cookie, waiting for the result. I would be very grateful for the answer.
