aqua - my baby was 4 days old - I was in hospital with him for 3 days after birth - their arrival was not welcome!! many swear words were said to dh when he told me they'd decided to come and 'help'!
Choosy - your mil sounds just like mine - I had instructions on how to feed (MIL didn't bf - seems her boobs didn't work or some such rubbish), how to hold, etc. etc. I wasn't even allowed to bath my own baby - mil said 'oh it needs an experienced touch!' (I kid you not)
Aqua - I have to say that Choosy's idea of asking someone to put them up is a good one - your house is far too small to cope with house guests ... especially, as you say, they are not terribly independent.
At 4 weeks, I got to the stage of thinking of working ds into some sort of routine - and I needed time and space to do it - on my own. If the pil come to visit, it's got to be on your terms - just like I imagine it will be with your parents.
Quick question - if pil are not going to be here at same time as your parents - can pil not use their flat?
Also - I'd count on babe being 2 weeks late - so 6 weeks from due date would be more realistic - that is if they're intent on being there for the magic 4 weeks ...
Another thought - sorry if rambling ... could you not go to see them for a spell? Not at 4 weeks, obviously, but at a few months?
going to go now, before my confused ramblings make everyone snore.
