DD will be turning 3 in February and has struggled with constipation/holding in her p00p her whole life. She has been on Miralax for about a year to help regulate her, and we try to feed her as much foods high in fiber as we can, which has worked pretty well to soften up her poop but she still sometimes holds it in and she's pretty particular about where she goes - ie she pretty much only p00ps at home. We've been on a fairly regular stretch of her p00ping every day or almost every day for the past 6 months or so but any little change to routine will throw her off and bring about a week or so of constipation/holding it in. (For example, we were away for Thanksgiving and she held it in the entire long weekend and it took a few days at home on schedule for her to regulate back again).
Recently, we've been talking more about using the potty and she's starting to get very interested in it. I've been having her "try" on a regular basis on the days we are home and we've had a few successes with p-ee. She's often dry during nap and for long stretches of the day and I feel that she's ready to be potty trained. I am planning on taking advantage of the 10 day break she has from daycare/school during xmas week to attempt to train her. I don't think it will be a huge problem for p-ee but I am really worried about p00p. The constipation is something she's struggled with her whole life and I don't expect that being potty trained will magically solve it, and may even exacerbate the problem. I would be fine to train her for p-ee, and keep supplying her with a diaper to p00p in initially, but is that confusing? I also don't think it makes sense to wait to potty train until she's "over" her constipation issues as that may be a long while or never.
Anyone else go through something similar? Tips for getting a p00p-shy child to learn to use the potty?
