Signs Your Baby Is Too Hot or Too Cold: Complete Guide

Getting your baby's temperature right is one of the most important safety tasks you have as a parent. Babies cannot regulate their own body temperature effectively — and being too hot can be dangerous, while being too cold can slow their development. Here is everything you need to know.

Why Temperature Regulation Matters

Overheating is one of the risk factors associated with SIDS (Sudden Infant Death Syndrome). On the other hand, being too cold can cause a baby's blood sugar to drop, making them lethargic and unwell. The goal is to keep your baby comfortably warm — not hot, not cold.

Never use a duvet, quilt, or pillow for babies under 12 months — use a well-fitted sleeping bag instead.

Car Seat Safety

This is a critical and often overlooked point: do not put baby in their car seat in a thick coat or snowsuit. The padding compresses in a crash and reduces the harness effectiveness. Instead, dress normally and use a blanket over the harness straps.
