Hi hun,
We got given gaviscon for Ava-Mae's reflux, however it made her so constipated. Like you we were given lactulose. Like you I didn't want to be pumping her full of medicine. But I read up on lactulose and it doesn't seem too mediciney (if you knw what I mean!)
"How does it work?
Lactugal solution contains the active ingredient lactulose, which is a type of medicine called an osmotic laxative.
In treating constipation lactulose works by increasing the water content and volume of the stools in the bowel, making them softer and easier to pass. Lactulose is made up of sugar molecules and is broken down by the bacteria that live in the lower part of the gut. This leads to the contents of the gut becoming more acidic, which reduces the absorption of a chemical called ammonia. The presence of ammonia in the gut causes water to be drawn into the lower bowel. This increases the amount of water in the stools, softening them and making them easier to pass, thus relieving constipation. It can take up to 48 hours for the lactulose to have an effect"
It really does work. It stopped Ava-Mae's poos being as small and hard as marbles!
In the end though we took her off the gaviscon. She didn't have severe reflux and I didn't think the benefits of gaviscon were worth the constipation.
I'm not sure if half a sachet would work though as I think at your LO's age (also depending on her weight) the dosage should be 2 sachets (although I am not 100%)
