Any mummies give this before to your LO?how?TIA

Yes I give this to my baby since second month. At first it was prescribed by our PD. Later on I realized you can buy this from Watsons bigger outlets. So I will stock up when Watsons have 20% sale. My gal used to be gassy quite often , I think this helps her gasiness and also her bowel movement. But she is 9.5mo now and eating solids three times a day. These few weeks she has very hard stools and this week she has not pooped for three days!! That's the longest so far so I am not sure if the probiotics is losing its effect.
