Sorry to hear DD is constipated. Its the worst. I find if DS gets really constipated the rectals suppositories work quickly and ease the back log. I put a bit of sudocream on the tip to help it go in. Sometimes he pushes them out while I am inserting it and while pushing it out manages to poop by himself.

I have heard another trick is to put sudocream or something like that on a cotton bud and insert just the tip and swirl it around. A Dr recommended this and the person using this method says it works a treat, quickly and to watch out for the explosion.. I have not tried it as I am too scared he will clench up and the the bud will be stuck up there and I will have some explaining to do lol.

My friends little one used to be bad for toilet training doing number 2's and hold on for days. She found Parochoc was a god send. I just googled it and says suitable from 12 months onwards.

I am not too sure on bf and medication.

Good luck. Its horrible to watch them being in pain.
