Mom’s Question:

My 4-month-old baby is not urinating. My son is acting normal – slept for 13 hours woke up happy but had a dry diaper when he woke. He ate like normal and now 1 1/2 hours later still has not urinated. Should I be concerned?

What To Do If Baby Is Not Urinating, But Not Sick

14 hours without peeing is a long time for a baby.  Could there be any reason why he would be dehydrated?

Some common signs of dehydration are:

  • Not looking well
  • Being more irritable than usual
  • Having a dry skin and/or a sunken fontanel
  • Urinating less than usual

The general guideline is that a baby should be urinating at least once every 1.5 hours and certainly not go without urinating for longer than 6 hours.

Has your baby eaten anything? Of course, if he sleeps through the night and hasn’t had any yet, then the amount of urine he would pass is smaller than if he feeds at night.

Most often, babies do pass urine, but the parents won’t notice. This is because disposable diapers are so efficient in soaking up the urine. If you tear his old diaper apart, you can examine the small beads in there. If they are warm or if they smell urine, your son has urinated.

It is possible that this is just a onetime event or that your baby has urinated and the diaper just absorbed it all, but I think you should still take this seriously.

If he hasn’t eaten much yet, offer him some milk. If he has eaten normal amounts and still doesn’t pee, then there could be some blockage, and more liquid could do more harm than good. Just take him to a doctor in such a case instead.

If he starts to become very tired or get a fever, is fussy or shows any other sign of illness or pain, contact a doctor immediately.

So to conclude, your baby is hopefully just fine, but do examine his diaper, offer some liquid if he hasn’t had any recently, and call the Dr – all right now!

Good luck,

Nov 25, 2018Don’t Over do it with the liquids
by: Anonymous


I am not a mom but I am a nanny and a nurse. I just want to recommend that if your child seems to have not urinated for several hours (you mentioned 13 hours, that is a significant amount of time) check the diaper carefully, you may be missing a small amount of urine. If you are unsure try wrapping him in a cloth diaper or a swaddling cloth for around 1.5-2.5 hours to see if he urinates (infants generally urinate every 1.5 hours)

If there is still no indication that he has urinated and you are confident that he is not dehydrated (normal feeding patterns and no diarrhea) do not try to force urination by filling him up with liquids. If there is a more serious problem such as a blockage, this can aggravate it and possibly do damage. If after trying the cloth diaper you still see no sign of urination, see your pediatrician.

As long as your child’s behavior is normal do not feel you must rush him to the emergency room. If you are worried you can always call the nearest hospital and ask to speak to the triage nurse. She will be able to asses over the phone how critical the symptoms are and give you a “soft recommendation”.


Jan 10, 2019My 3 month old child is not wetting his diaper as often

by: Anonymous

My 3 month old child has a cold. His symptoms are coughing, congested, runny nose, pink or rash on face, body, between skin folds. His void is colored yellow and a slight tinge of green. His diapers are dry for about 6-8 hrs now, but my wife and I noticed a slight pinkish color on his diaper where his urine usually is. He is breast feeding well and smiles and is attentive, but we’ve noticed him sleeping more often now. After he feeds he is irritable. He cries when he coughs because of his runny but sometimes clogged nose and congestion sometimes causes him to gag. We’re hoping he doesn’t have UTI.
