Sleep Training at 17 Months

Methods at 17 Months

Ferber and CIO continue to be the primary recommendations. At this age, the approach is essentially the same as for any toddler, but you may need to extend Ferber intervals slightly (start at 5 minutes instead of 3) since toddlers can sometimes escalate more with very frequent check-ins.

Pre-18-Month Regression

The 18-month regression often starts creeping in around 17 months. It's driven by a huge language explosion, emerging independence ("I do it myself"), and separation anxiety that can resurface. If your toddler was sleeping well and suddenly starts fighting bedtime, this is likely the cause.

Key Strategies

The 18-month regression is real, but the worst thing you can do is abandon your approach. The regression passes in 2-4 weeks. New sleep crutches introduced during it can last months.
