Just returned from HK. DS has jetlag and is sleeping. Should I wake him to get him back on track? Also, he slept in our room on hols and often in bed with us due to the jetlag going out. Now he won't sleep without being rocked or in my arms. He was doing well before we left. I could leave him when tired and he would go to sleep on his own. Now he has to be held and if I put him in cot he stands up and gets cries. Will he ever get back to before?
