I now have sufficient information from authoritative pediatric references to give a comprehensive answer. Let me synthesize this.
Here is a structured evidence-based approach to constipation in a 14-month-old:

Constipation in a 14-Month-Old — Treatment Guide

Definition & Recognition

Constipation in toddlers is defined functionally as: ≤2 bowel movements/week, hard/pebbly stools, painful defecation, or straining. At 14 months, this is most commonly functional constipation — no underlying organic cause.

Step 1: Dietary & Lifestyle Modifications (First Line)

These should always be tried first and continued alongside any medications:
  • Increase fluid intake — ensure adequate water/milk daily
  • Increase dietary fiber — fruits (prunes, pears, peaches), vegetables, whole grains
  • Prune juice — particularly effective in this age group; 60–120 mL/day can be tried
  • Reduce cow's milk if the baby is drinking large quantities (>500 mL/day), as excess cow's milk is a common contributor to constipation in toddlers
  • Regular physical activity and tummy time

Step 2: Medications (if dietary changes insufficient)

Lactulose (Osmotic laxative — preferred first-line in infants/toddlers)

  • Dose: 1.5–3 mL/kg/24 hr orally, once daily to twice daily
  • Max dose: 90 mL/24 hr
  • Soft, well-tolerated. May cause mild GI discomfort or flatulence
  • Avoid in galactosemia; use with caution in diabetes
  • Can be mixed with juice, milk, or water

Polyethylene Glycol (PEG 3350 — MiraLax)

  • Evidence from randomized controlled trials supports PEG as effective for improving stool frequency in children
  • Dose: typically 0.5–1 g/kg/day dissolved in fluid (though Harriet Lane notes it as first-line in children; confirm dosing with prescriber for <2 yrs as formal labeling starts at age 2)
  • No serious side effects; tasteless when dissolved

Magnesium Hydroxide (Milk of Magnesia)

  • Dose for <2 years: 0.5 mL/kg/dose once daily–QID (using 400 mg/5 mL preparation)
  • Use with caution: monitor for hypermagnesemia; avoid in renal impairment
  • Not first-line in very young infants, but usable in toddlers under guidance

Glycerin Suppository

  • Useful for acute relief of hard stool/rectal impaction
  • Safe for infants; insert infant-size suppository rectally as needed
  • Not for regular/chronic use

Step 3: Fecal Disimpaction (if impaction present)

If the baby has not passed stool for several days and the abdomen appears distended or a firm rectal mass is felt:
  • Rectal disimpaction with glycerin suppository or saline enema (infant-sized) under medical supervision
  • PEG high-dose oral regimen can also achieve disimpaction over 1–3 days

What to Avoid

AvoidReason
Mineral oil (oral)Aspiration risk in children <5 yrs; not recommended
Stimulant laxatives (bisacodyl, senna)Not first-line in this age group; use only short-term if needed
Castor oilNot recommended in infants

Red Flags — Refer or Investigate Further

If any of these are present, an organic cause must be excluded:
  • Constipation from birth (consider Hirschsprung disease)
  • Failure to thrive / poor weight gain
  • Abdominal distension with bilious vomiting
  • Blood in stool (beyond anal fissure from straining)
  • Developmental delay
  • Abnormal thyroid / metabolic labs

Practical Summary

ApproachAgentNotes
First-line dietaryPrune juice, fiber, fluidsAlways try first
Osmotic laxativeLactulose 1.5–3 mL/kg/daySafe, well-studied in infants
Alternative osmoticPEG 3350Evidence-based; confirm <2yr dosing
Acute reliefGlycerin suppositoryFor rectal impaction
If no responseRefer to pediatrician/GIRule out organic cause

Note: Always consult a pediatrician before starting any medication in a child under 2 years of age, particularly for dosing confirmation and to rule out underlying causes.
