How many pouches/squeezes to you give your baby?

I feel like this is a silly question but I really have no idea.. is there a limit daily we should be giving them? My son is 1.5 and currently I limit it to 3 -4 a day. I see that they are healthy and I buy the ones that have the most natural ingredients. I get the all veggie ones and all fruit ones and he sucks them all down. He eats breakfast, lunch and dinner food regularly so it’s not effecting his real food appetite, what’s your suggestion?
