Sorry, my attention was diverted. I just read your question. A bath is a good solution to constipation and so is activity in general. If you let her roam around for a little bit on the floor that will probably stimulate her. What you also want to look at is why she is constipated to begin with. Constipation is a symptom of low humidity and/or high temperature. High temperature, ironically, can occur when the cage temps are cool and the snake stays on the warm side all the time. Making sure your humidity levels are appropriate (over 70 at minimum, over 80 their sheds are very good) and that she has a gradient where she can thermoregulate as she digests are two good ways to avoid this. Another two ways to avoid constipation is by waiting to feed again until after she defecates ( a normal evacuation comes about 4 days after eating so it should work out perfectly even for young Burms) and to let her exercise regularly.
