Why Florida Babies Overheat So Easily

Florida humidity changes how babies feel overnight.

Even when room temperatures look normal, trapped moisture in the air can make sleep feel much warmer.

That’s why parents often notice:

• sweaty hair
• damp necks
• short naps
• frequent night waking

And honestly, overly warm sleep sacks can make all of that worse.

Our Final Recommendation

For Florida babies who naturally sleep hot, we’d prioritize:

• lightweight bamboo sleep sacks
• 0.5 TOG when possible
• minimal pajama layering
• strong airflow in the nursery

The lighter the overnight setup felt, the calmer our baby slept.

And honestly, that mattered far more than extra softness or thickness.
