Signs your baby is too cold

The immune system of a baby or infant is not as strong as an adult. They cannot regulate their body temperature according to weather conditions like adults. They need external measures to be taken by their parents to keep them warm in winter and cool in summer.

A sudden temperature drop can cause be a risk to the health of a month old baby. You might some need to watch your baby sleep to keep an eye on the body temperature of your baby. The room temperature in the room is also important and should be monitored using a decent room thermometer like this.

You might need to make sure you allow fresh air into the room if it gets too hot and shut any open windows if it gets cold.

To monitor the body temperature of your baby, here are 5 main signs to observe:

  • Cold Hands & Feet

It might be obvious, but the first sign that your baby is cold is from their hands and feet. The hands and feet are the most exposed points in the body as the heat escapes faster from hands and feet. A baby forehead or ear thermometer (See price on Amazon) is a must-have for your home because there should be no difference between the temperature of these two points and other parts of your baby’s body. So, if you feel your baby’s hands and feet cold, use the thermometer to check, then put on an extra layer if necessary.

  • Pale Skin

Another sign that your baby might be feeling the chills is if you notice that they have pale skin. If the skin is more pale than normal, it means your baby might need warming up. This could also be a sign of hypothermia and you should do what you can to avoid your baby getting to this stage. In this situation, you should wrap them up in a blanket or slowly warm them up.


  • Being Fussy for No Reason

If you feel your baby is being fussy for no reason, then it there’s a chance they’re cold and it’s worth checking. If this happens, cover the hands and feet first, then wrapping up in a blanket will help.

  • Sneezing

This situation is related to the brain sending messages to the body when it detects the temperature in the room drop. A part of the brain thalamus controls the temperature of the body. If you see the baby starts sneezing, it is an obvious indication that your baby might be cold. Sneezing can also occur when baby nappies are being changed. At times like this, it is quite normal for sneezing to happen.

  • Still & Quiet

If your baby appears to be still, quiet and lethargic, then there’s a chance your baby is unwell and feeling the chills. The initial signs of hyperthermia are quite similar. Infants – due to their lower immune system – are more vulnerable at times like this.

Most doctors would suggest that if your baby is quiet and not moving around as usual, then you should not ignore this and should take action. Just take your baby into a warmer room, use this baby snuggle blanket or wrap your baby in a blanket.
