We had too many visitors at hosp (family and all their partners etc) with DS. This time we're only telling my mum when I'm in labour (so she can look after DS) and then we'll annouce it when he's born and we've had a few hours to ourselves and DS has met the baby. If it's a straight forward labour (i.e. if i dont tear again) and I get home within a few hours, we'll just tell people when I'm home! DS was born at 11pm (after 26 hours of contractions), so luckily had a few hours to recover a bit before people showed up!
we invited mil to come, so mils sistes wanted to come too...neither could drive, so DHs cousin drove them. So that was 3 visitors from inviting one.
Similarly DHs sisters were invited, they came at the same time as the other 3 and one bought her BF who I work with (and don't know), it was very uncomfortable for me and I cried when they left, after having a very emotionally balanaced pregnancy with hardly any tears!
