My in laws had their first grandchild around 6 months ago. They live close to them and see them a lot daytime and evening. The babies bed time is the parents bedtime so the baby is up all evening with them and goes to bed 11 or 12 ish. That's what works for their circumstances. I'm hoping at the right time my baby that's due will have more of a 7pm bed time routine as it will suit my circumstances. We live a distance but will stay with my in laws from time to time. I'm anticipating it may be hard to maintain this routine on these visits. They often have people visit them in the evening or go to family friends houses and the first grandchild will always be there and up and in a very different routine. My question really is how do babies cope with a few days every few weeks of a totally different sleep routine to the one you have at home? Will it create a nightmare the next day or when we get home? I want to be flexible and not too regimented but I don't really know how this will work. Any advice would be great. Thank you. x
