Most people think a baby is ready for slumber when her eyes get lidded and her head slumps against our shoulder. 

Actually, at that point she is overtired.

Many tired babies can sleep anywhere, anytime. But those with a challenging temperament or poor state control live on a tightrope. Growing weariness can suddenly tip them off balance and send them crashing down from a happy alertness to exhausted misery in a blink.

So if your well-meaning neighbour says to keep your tired baby awake during the day to boost her sleep at night, do not do it! This strategy may work for adults, but it usually backfires with babies, leading to bigger struggles falling into sleep…and staying there.

In his classic book Healthy Sleep Habits, Happy Baby, sleep expert Dr. Mark Weissbluth states, ‘Sleep begets sleep.’ He is right…and that is why experienced parents put their babies to sleep before they get overtired.

Signs of an Overtired Baby

As shown in the sample 2-month-old schedule above during these early months, your best bet is to put your little bug in bed after 1.5 to 2 hours of wakefulness, hopefully at–– or just before­­––she shows these early signs of an overtired baby:

  • Reduced activity, smiling, and talking (or even frowning!)
  • Yawning
  • Staring, blinking, and rubbing the eyes
  • Increased fussing

As time goes on, it will get easier and easier to recognise your little one’s sleepy-time cues. Putting your baby down before she shows signs of being overtired and cranky will not only be easier for you, but it will also set her up to get the best sleep possible!

What do you do when an overtired baby will not sleep?

It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
