Hypoglycaemia (low blood sugar levels) in newborns can sound scary - but understanding the signs early can help you feel more prepared 🤍
It most commonly presents within the first few hours after birth, as your baby adjusts from the womb to the outside world.
As your baby adapts, they begin using energy on their own. For most healthy, full-term babies, this transition happens smoothly.
But for some babies especially those born early, smaller, larger, or to mums with gestational diabetes — they may be at higher risk.
Signs your baby may have low blood sugar include:
• Jittery or shaky movements
• Not feeding well
• Feeling cool or having a low temperature
• Rapid breathing
• Being very sleepy (lethargic)
• A weak or high-pitched cry
If you had gestational diabetes, your baby may have been exposed to higher glucose levels during pregnancy.
After birth, when that supply stops suddenly, their blood sugar can drop which is why monitoring is important.
If your baby is at risk, your care team may check their blood sugar with a small heel prick test in the first few hours after birth.
Treatment is usually simple and focused on supporting your baby:
• Feeding (breastmilk, colostrum or additional support if needed)
• Keeping your baby warm
• In some cases, glucose gel or further support may be required
Ways you can help support your baby:
• Skin-to-skin after birth
• Keep baby warm
• Offer a feed within the first hour (if able)
• Feed regularly (every 3-4 hours if advised)
Early recognition is key but you won’t be doing this alone 🤍
