My 5mth DS has slept in his cot, car seat or push chair from day 1 and has done very well. He has learned how to get himself back to sleep from his naps in the day and just moans before having another 45mins kip. I need him to get used to sleeping in a travel cot so that we can visit family over Xmas and go on holiday etc. We tried him in it today but he woke after 45mins and then cried for nearly an hour before he was able to get back off. If he doesn't get at least 1.5hours over dinnertime DS is really grouchy all afternoon and we don't want to spend Xmas at people's houses with a really cranky baby! Do we persist and do cc?? Has anyone else out there had this?
