Sleep Disruption Troubleshooting

Common sleep challenges at this age

Teething Pain

When: Can begin around 4–6 months and continue through 24 months as teeth erupt.

Signs: Increased drooling, gum rubbing, irritability, refusal to feed, disrupted night sleep.

What helps: Offer a clean, chilled teething ring. Gently massage gums with a clean finger. Maintain consistent bedtime routines. If pain is severe, consult your pediatrician about appropriate pain relief.

These are typical ranges, not prescriptive targets. Always consult your pediatrician for questions about your baby's feeding, growth, health, or sleep concerns. Follow safe sleep guidelines: place babies on their back on a firm, flat surface with no loose bedding.
