Right, so, not particularly structured, but yesterday morning nap I tried PUPD, and after 25 mins of the worst crying I've ever heard him do and 10 PUPDs, he seemed to just give up and drift off with me shushing loudly and patting him on his chest. It was sad, but also felt successful. Rest of the day was just 'normal' sleeping on walks because it was a nice day and fed to sleep at bed time.
Day 2, the same. PUPD for his first nap. Was just as hard as day 1. 35 mins of crying, then just gave up and fell asleep. And again, we've been out most of the day as it's been nice.
Is this pointless? Do we just do it for the naps we can (we've been out the house because it's nice, and because people are coming to view the flat as we're trying to sell), and hope this contributes to him learning to sleep on his own or MUST it be a concerted effort for every nap and bed time?
Sorry, still no timetable. But this morning he woke at 7, then we started PUPD at 9:30 and he fell asleep for 45 mins at 10:10.
