My son is now 10 weeks old and we have been using brauers colic relief for about 4 weeks now. I dont use it after every feed. Usually only once or twice a day and it seems to work well for him then. but i want to know if it is ok to keep using it on a regular basis? we have used 2 small bottles already. is it ok to keep using or is it something you should only give them for a few weeks then stop?
