he's taken to waking at 2 or 3, having a feed, and instead of nodding off again, he is babbling and wants to play. Last night we were so fed up, we put him back in his cot (in our room as we have nowhere else to put it) and he just stood there screaming until we picked him up, whereupon he was quite happily babbling away and wanting to interact.
We have never played with him at that time, give him no indication that we want to do anything but sleep. He'd even started sleeping through occasionally, but now it's like he's wired to the moon at 3 am. He is teething, but I would have expected that to manifest itself more as whingeing than chirruping away.
He doesn't seem especially hungry (I offer both boobs, and sometimes he won't have the 2nd), and he's not napping particularly well during the day - maybe 2 hours total naps, then we get him ready for bed by 7.30, and are lucky if he's asleep by 9. He is rarely getting more than 11 hours total sleep in 24 hours, which would suggest he's chronically undertired, but he's perfectly chirpy most of the time.
Has anyone else experienced this, and solved it?
