We're going to my mums today and all the family will be round...lots of noise, my mum going crazy with the stimulation toys and nowhere quiet for LO to sleep. will she be ok to be awake for 7-8 hours? i've put her down for a nap now and hopefully she'll sleep for a couple of hours. she will grizzly when she's tired but will be fine after a few mins and just keep going if she has stimulation, but her eyes get steadily redder so i know she's tired. will she be ok?
