The short answer

You're doing a great job, and your baby is normal. In the first year expect frequent waking, catnapping, growth spurts, the four-month regression, teething, and separation anxiety, all completely typical. Circadian rhythm settles around 10 to 12 weeks, and one to two night feeds stay normal for months. Lean on routine, connection, and adequate nutrition rather than cry-it-out.

Pre-kids, I had no idea of the magnitude that sleep (or the lack thereof) would impact my life. There is a plethora of information at our fingertips, telling us when our baby should be sleeping through the night; and if we don't meet these expectations, then we somehow feel like a failure of a parent - or something must be wrong with our baby.

I really feel the need to set the record straight: you are doing a great job. Your baby is perfectly normal, and you are a good parent. And with the intention of making you feel a little more normal, and a little less concerned - here's what you can really expect with sleep in the first year:

0-3 Months:

Additional Tips: * Placing your newborn in a light room (or next to a window) for nap time in the first 6 weeks (and dark room thereafter) will assist with developing their circadian rhythm and preventing day/night confusion - as will ensuring your newborn doesn't sleep too longer stretches during the day (two to three hours maximum) and feeding on demand (every two to three hours). * Respond to your babies cries accordingly. Allowing them to 'cry it out' may curb the crying and eventually "train" them to sleep - but for all the wrong reasons. Afforded the opportunity, babies are more capable of self settling after the fourth trimester (between three to four months).

4-6 Months:

Before I could really answer this for you, I'd ask two things.

Tap one and I'll start your plan there. No judgment — there never is.

Not all children will be affected by change and transition in the same way. Although in the minority, I know of babies who have woken in the morning with brand new teeth without as much as a grizzle, and those who make it through the first 12 months almost unscathed by developmental leaps! Despite the developmental and environmental variables, here are five things we CAN do to ensure our baby sleeps the very best they can given their current circumstance:
  1. Implement a consistent routine from three months.
  2. Optimise their sleeping environment.
  3. Be respectful of your child's current developmental stage and accept that regression is normal.
  4. Nurture the parent-child connection (the majority of sleep difficulties are fear related - the perfect antidote to which, is establishing safety through love and connection!).
  5. Ensure adequate nutrition.

"You are a good parent, you are doing your best, and you are enough."
