Thank you for your advice , ill do that
I would try and get her off the movicol, it can cause the bowels to depend on it over time (in my experience, I’ve had chronic constipation since I was a child and started on movicol and my body became dependent on it). Lactulose is what I use on my daughter when she’s a bit bunged up and I’m able to up the dose and decrease it just based on her needs and she comes off it for long periods no problem.
Maybe speak to your health visitor about doing an allergy test? Then they can sort out a dietrian so you don't have to use meds all the time. We use lactulose when our LO gets constipated
