Hi, mamas! I usually just post over on October 2014, but decided to hop over here for some advice about toddler constipation. So hello!
Backstory: My DS (2.5yo) struggles with chronic constipation. It's most likely from a combination of diet (kid loves bananas, yogurt, and cheese and refuses to eat fruits, veggies, smoothies, etc...but we really do try, and offer healthy options all. the. time.) and ignoring the urge to go/trying not to poop for fear that it will hurt. "I don't want to poop right now." is a common sentence we hear in our house.
Pedi has prescribed 1tbsp Miralax daily, and we also give him activia yogurt and try try try to get him to eat high-fiber foods. We also constantly offer water.
Last weekend we went out of town to visit relatives and forgot then Miralax. He went a few days without a BM, and then he only produced a very small, hard, and dry poop.

Back home, we started up the Miralax again...only, no poop! He has been grouchy and complains that his tummy hurts off and on, so since the Miralax seems to not be working, we gave him a liquid glycerin suppository yesterday. Within an hour, that produced one very small poop...like way too small to have actually cleared any blockage. Today we gave him a regular child's glycerin suppository, but no poop! Not even a smear! He was able within the hour to push the suppository back out but hasn't pooped at all all day.
I'm going to call the doctor in the morning because Miralax not working and 2 failed suppositories has me so worried...what else is there to do? He has had a warm bath today, he gets lots of exercise, running and playing outside, has had about 6oz of prune juice and lots and lots of water. Says his tummy hurts. Says "I don't want to poop right now," and wants to be held nonstop. Poor kid.

Does anyone have any other ideas I can try? Tricks to help your toddler poop? Does anyone know what the next step is, that is, what they will do at the doctor for him? Thank you!!
TL;DR My toddler is chronically constipated and I've tried everything I can think of to help him (bath, juice/water, exercise, Miralax, suppositories...and NO poop). I need some more ideas! TIA!
Re: Severe Constipation Issue
We are also supposed to limit dairy products and other binding foods, and increase fruit and veggie intake. lol - this is the hard part. My first plan is to make smoothies to replace yogurt, and to hide the bananas in the pantry. :P The real fight will be over WCM, but a small glass each day shouldn't hurt if I'm limiting other dairy intake, and hopefully will be enough to satisfy him.
Gave him the MC this afternoon and still no poop, so we'll see! I really don't want to have to give him another dose. Thanks for the advice and support, ladies!
The magnesium citrate did NOT work!
ETA: His doctor thought that a dairy sensitivity might produce gas and diarrhea more so than constipation. Thoughts?
The glycerin suppository didn't work this time either. I'm at a total loss. I suppose we'll call the doctor AGAIN in the morning, but I don't know what they'll do next. Poor baby.
I'm also afraid of what will happen once he does expel the blockage...he is full of mc, Miralax, and prune juice...I'm afraid it won't be pretty.
Fingers crossed for huge messy poops tonight. Rather than none, anyway.
I really hope he doesn't have to go to the ER. How traumatic that would be...and I don't know what they would do there? Ugh. ...poop, boy! Poop!
She also referred us to a pediatric GI specialist, so we will go to the specialist to try to determine what the underlying cause of his constipation might be. I'm so ready for this to be over.
Thanks for the support and suggestions!
So DS apparently taught himself that the more comfortable way of relieving the need-to-poop sensation is withholding the poop, inadvertently making pooping worse and causing himself to become more and more constipated.
Basically, the GI prescribed Miralax until DS is potty trained. We are supposed to interrupt him when he shows signs of trying to avoid pooping, and either ask if he wants to sit on the potty or just have him sit in our lap. We can also try teaching him to tense and relax, tense and relax, by making tight fists and holding his breath, then blowing out and opening his hands, etc.
I would keep a close eye on it. Jack has had to have some pretty extensive work done the last 2 years HOWEVER. I don't think my sister is as proactive about keeping them cleanly all the time.
I'm not sure any of this helps you, but just wanted to say I've been there, and it's a challenge. I really hope this time we'll nip it for good, it's so hard to watch them go through it.
I like that he's doing so well, but I AM concerned about his teeth. I'll look into Lactulose, and if it doesn't pose the same risk as. Miralax for dental health, I'll give our GI a call to ask about that as an alternative.
