Thanks for that Nicola, its interesting to see. We were doing same but he was waking at 6am hence our reason for thinking the 5hr A wasn't long enough & he was UT. That said, we haven't quite been having STTN, we've been having a crying NW at 10/11pm ish & then sometimes some early morning restlessness. This is why we've pulled the nap back to 12.30 to give him the extra A time to BT, but TBH I think he needs more in the AM too. Actually I'm rather lost with it all! I'm pretty sure he's OT tonight, so tomorrow will probably be a long nap & start all over again. Bah!
