Yes

My DD settled herself into a short am/ long lunchtime/ pm CN pattern from a very young age. Short naps in sling and at lunchtime I would help her extend (while DS1 was asleep), and that became her natural pattern. By 4 months she regularly refused the pm CN so would go from 2.30pm until a 6.30pm bedtime
. She would BF and then sleep until 2-4am, the sleep until morning (although she was often windy at this time as they often are).
At 5/6 months I realised she needed feeding before a nap else she would SN, and she went onto 2 long naps and a great EASY for her day. NWings increased, and we carried on like this until she was about 8 months, until she was waking every 1-2 hrs and EWing as well. I was BFing her back to sleep each time.
I started capping the am nap, and she went back to sleeping more sensibly. I stopped BFing at 9 months and she STTN
. That was on a 30 min am, and 2hr lunchtime nap. At about 10 months she went to one long lunchtime nap.
She isn't actually LSN - she has always done 12 hr nights and really likes her sleep far more than my DS1 (who really is LSN
) - but she did need that long afternoon A to sleep properly at night. Outside of BWer it is actually a pretty common baby routine, so I guess she isn't the only one that likes it.
I did have to 'push past' her tiredness, especially when moving to 1 nap. She was set in her routine so used to be tired when she 'should' iyswim? She followed the clock and then didn't sleep at night to make up her A time.
Go gentle of course to avoid a great big mess - but stretching as best as you can will likely end this sooner I think.
