We've been doing set nap times since E was around 8 mths old & his nap times have stayed pretty much the same since then (give or take 15 mins). I also did set naps with DD (I know quite a few people on this site use them too), but as with all things it doesn't work for all LO's & may not fit into your lifestyle or your LO's needs iykwim? For me I hated the unpredictability of having to work out A times every morning, I was never very good at it & every day was different. Also, as I have DD, I have places that she needs to be at certain times such as nursery, activities etc so I really needed a predictable & consistent day as much as possible to make things easier.
I think our times are WU usually at 7 (but could be between 6-7, I wake him at 7am if he's still asleep), nap 1 at 10am (usually 1.5hrs), nap 2 at 2.45pm (usually 1hr), bed at 7/7.15pm. It doesn't matter if he has a short am nap as he makes up for it in the pm nap.
I set the nap times then stuck it out for a few days and he started knowing that it was sleep time and he started sleeping longer and more reliably for each nap. E automatically gets sleepy as soon as it was 10am even if he was only up at 7am as I think they just become used to the routine iykwim?
With DD, as she got older and needed less sleep, I kept the second nap at 2.30pm and started to cut the first nap to 45 mins but that was not until she was around 14 months so we had the same routine for 7 months. Then she dropped the morning nap and went to 1 nap at 12.00. It was a really simple nap routine and one that made the 2-1 switch really simple. Hope this all makes sense?
