My little one is 19 months and her sleep has never been great. We’ve had a few spells of her sleeping through but she still doesn’t reliably do that. More often than not, she wakes at least once a night and can either take an hour plus to get back down or we have a disturbed night co-sleeping. I’d kind of thought it would eventually settle and certainly by 18 months. In your experience, will this resolve itself without sleep training?
