At christmas I'll be visiting friends and relatives for 2 weeks with DD who will be 4 months by then. We are co-sleeping and usually in bed together by about 9. Obviously at Christmas I might want to be a bit more sociable and stay up later! So I was wondering what I should do r.e sleeping arrangements, particularly as there are smokers in one of the houses we are staying, so that means it is not safe for co-sleeping right? DH suggested a travel cot, but I'm not so sure this will be a good idea as she's used to co-sleeping and I'm already worried that all the travelling will be unsettling for her. At 4 months is this still an age where she would be happy to sleep in her sling, early evening, and then come to bed later with me? Even if there are distractions such as talking, people around? Or would it be better for someone to go with her into a quiet room when she sleeps as I know you shouldn't leave babies less than 6 months alone to sleep. I am really worried that the whole trip will be overstimulating for her, and just want to make sure that she sleeps well!
