I'm saying I don't just want to tell him and wash my hands of the problem. I'll tell him but I'd also like to give some direct help too. Like babysitting, maybe buy her that Brooke Shields book someone mentioned. Any ideas like that I'm open to hear.
Having a newborn is a 24/7 job for the first few months. Buying this woman a book just isn't practical. You should be talking to the husband ASAP and offer him any support he needs. Having a first baby is a huge shock to the system for both parents and I'm sure he'd appreciate your offer to help.
Also, babysitting ins;t a practical idea either. the kid is being breastfed and will need a feed every few hours. I can promise you, mum and dad wont feel like jumping in the shower, getting dressed up to go out for an hour while their brand new baby is lying at home with you.
My advice is to not ask them what they want; its too fucking hard to think of what you want or need when there is a new baby around. Instead, Cook up some awesome food that can go in the fridge and be re-heated and just take it around. If you get there and you can see the floor needs a vacuum and it's possible to do it, then do it. These basic day to day things were 10 times the help than all the other crap people tried to do for us.
Remember: Food. Big comfort dishes like homemade lasagna or a slow-cooked curry or stew that can go in the fridge were god-sends and so were things like homemade pastries that could be eaten cold (or re-heated) - just remember, don;t take anything around that has to be eaten straight away or requires any kind of effort to cook.
one last piece of advice: judge carefully how long you spend with these people. Its awesome that you want to help, but constantly having guests over (who get to go home an have a good sleep) can be tiring all on it's own.
Good luck.
