I hope they find out about your book of rules beforehand, and decide to stay at home. What makes you think they'll want to be welded to you & your house & baby all day & evening anyway, and your DH will spend time with them won't he? Won't that include taking them out?
I hate the way these posts/threads about overseas family coming to visit newborn baby & mum over here. Whole implication is these foreigners are oiks, they need rules & regulations, they and their culture are so DIFFERENT that means they will DEFINITELY want to handle baby all day, listen to my scintillating convo all day and nothing else, them coming for a few weeks out of year is a catastrophe beyond measure and, horror of horrors, they don't speak English!!!!
Its a real shame to marry a man but look down on his culture and family and dictate as if he had nothing at all to do with making baby. Why marry into another culture then scorn it? Its your baby's heritage too. Yes 5 weeks may seem long to some but in many cultures, mine included, its perfectly normal. & the remit is to be an extra pair of hands and help new mum with chores and getting a rest, relatives don't come over to sit round-eyed in awe, they muck in and help and will leave you entirely to it when you want to sleep. They know new mums need sleep and could do with housework help. They're not stupid just because they don't come from the UK!
Superiority complex gone mad
OP with all those rules you know you don't want them there and 5 weeks is too long for you anyway so just tell your DH, why over-complicate it? Im sure he won't want to subject his family to all that, they can stay in hotel problem solved you can keep them all at arms length and soldier on through.. oh thats if you're not then going to dictate re. your DH spending time with and visiting them at hotel because if they sense you don't want them at yours they won't want to be there, will they?
