I don't think that's unreasonable that u don't want everyone there 5 mins after the birth all crowding & pawing at the baby.My mum was there during the labour last time but she just sat quietly in the corner & she didn't even touch the baby until after i'd had a shower & got settled,& then she asked b4 she did.My brother came up to pick up my mum so i saw him for about 10 mins but other than that i didn't see anyone else for about 24 hrs (except hubby of course) oh & my Dad bought my kids up the next evening of course .My inlaws would never make demands like that & even if my MIL did get a bit over excited & want to rush up to the hospital straight away my hubby would set her straight anyway
