Sara - no probs eh they are all different! The only thing is here, Alon was doing short 1h 15 naps with 6.5-7hrs A, was waking crying a lot & he's only been on 1 nap for a month. We've suggested shortening b/c for a just turned 1YO 7hrs A before nap is pretty huge - compare this to Z with his 4.5hrs IYSWIM?
Ima, I personally found that within a week or 2 of switching to 1 nap we also got very short naps of 40-45 mins & for us this was plain old OT, & within a few weeks, his naps consistently lengthened to 2hrs+. All I am wondering is if you had given it a bit more time with a say 5-5.5h shorter A & done some earlier BT's whether that nap may have actually lengthened all by itself IYSWIM?
Reading what's happened over the last month & noting that you did get a few days of great naps with the 5h 20 A, I would probably shoot for 5.5hrs. I actually think the key to your issues might be that A time to BT though hun. I know on 2 naps a lot of people keep the first & second A times exactly the same, but this won't necessarily work on 1 nap. If Alon is doing an A time before his nap of 5.5hrs, its unlikely he will also handle another 5.5hrs A to BT (especially so if the nap is short). Of course if he does a monster nap of 2.5hrs+ it may be a different story! I have found with my LO that if he does a 5.5hr A in the morning & a 2hr nap he needs no more than 5hrs A to BT. He's 18 months so you might find Alon needs less (of course they are all different
). I just wonder if you are able to keep ontop of any OT that way, whether the nap might extend once he's that bit better rested.
And if this doesn't help, but he starts waking happy again (rather than crying like at the start of this thread) then I will eat my words & say 'ok go for it - this boy needs more A'
But as I said before, once you go upwards of 6hrs you really are heading into nap capping territory & IMHO he is a little young for that having only just transitioned to 1 nap.
