I would let him sleep as long as he needs today. I agree he sounds OT and hyper, not UT. J gets like this and then it all comes crashing down one day
. Just let him sleep, then I would probably offer an EBT too as normal 7pm BT is likely to cause OT from too long a day. When we get into this sort of a mess (as you know with a LO at nursery it happens fairly often) then I usually do a day of nap when it's needed as you've done today, then try to get back to normal naptime but stick with BT on the earlier side until I'm sure she's caught up. It usually takes a few days here before we get back on track, longer if teeth are in the mix. I find teeth increase J's sleep needs, more than I expect, and just wondering if that's what's thrown everything off for you too?
