Up until the last week, DD has been pretty regular in her 'bed at 7, asleep at 7.30' routine, but for the past five nights she's just stayed awake intermittently babbling and crying - we've had to go in to her a few times to calm her when she's started getting into a state, and given paracetomol on a couple of occasions as she has back teeth coming through, but previously she's not been as unsettled for as long with teeth. It's only when it gets dark she starts settling, so around 9-9.30 - however light evenings haven't been a problem for her until this week. It's also hot, so she's just in a vest/babygrow instead of having a grobag or blanket, so that's changed too. Not sure if it is any or all of the above contributing to the change! She's still getting up at the usual time in the morning but is getting tired earlier in the day so obviously needs the sleep she's missing out on.
Please tell me this is normal and will pass and we'll get our evenings back again! (Am pregnant at the moment and knackered, my bedtime's 9pm most nights so really could do with her settling before then!)
