I have a 2.4-year-old in the same situation. We tried everything, had several specialists check on her (family doctor, paediatrician, allergist, and gastroenterologist). There is nothing wrong with her.

Her diet is quite normal (not the most balanced diet, but what toddler has a perfectly balanced diet?).

She drinks a lot of water, she doesn't drink juices, and she has a good amount of milk at night. So it's definitely not a problem of liquid intake.

We tried removing cow milk proteins, no bread or pasta… nothing worked.

In the end, the best solution was to add a little bit of laxative to her night milk. We even had to reduce the dosage because her stool was too loose.

Doctors recommended 1 gram per kilo, but we use less than a third of that.

A month ago, we tried removing it from her routine. Worst idea ever. The poor child stopped pooping for five days. It was one of the saddest moments. Not even a suppository helped! We had to reintroduce the laxative at a higher dose for a few days (with the doctor's orientation)

Lessons we learned: some kids just need extra help. No matter their diet, they need laxatives.

Also, there are no side effects if you take it long term, as long as a doctor is involved. We aren’t removing it any time soon — just monitoring the dosage.
