6 month old waking same time at night- habit?

Thanks Kelly. Bizarrely last night was quite good with her only waking twice and dummy both times settling her back quickly. Only thing different yesterday was that we were out for her second nap and something woke her up in town so she only slept for about 45mins (having slept for 1.30hr in the morning).  Maybe she needs a shorter afternoon nap? But tbh I think it's all just random and like you say it's just a time to ride out. She seems to have a patten of a bad night for one reason or other then the next not so bad, next after that less bad etc...so hopefully that is what is happening her. Thanks for all of your help :-)

Fwiw my DD won't nap longer than 45mins in the car. We get no naps at all if we're out and about  . It's just as they come out of a sleep cycle and it's a different place, all of a sudden they're raring to go!!
