frouby that's rubbish. I sympathize too- there's nothing worse than people acting all helpful then not actually helping when you really need it!
I can relate a bit- when I had DC1 my mum wasn't all that helpful but the worst thing is she thought she was! I was totally shell shocked my life turned upside down and she'd swan in every few days for an hour and sit and have coffee and a chat when all I wanted was her to come for a bit longer (I'd have rather she'd come over loads the first week or two then less if need be) help out with cleaning/sorting the house out, letting me nap and look after baby etc. but she just didn't think I needed the help and I'm too polite/stupid to tell her! She actually said to me one day that I had a 'face like thunder' the first few days after DC1 was born- I thought yeah that's cos I needed some bloody help!!
When DC2 came along I was hoping for her to take DC1 to the park or be a bit hands on with the baby so I could rest but no, it was the same.
This time she mentioned she wanted to go on holiday in the New Year (so potentially a few days after baby is born) for a holiday in St Lucia with her bf if there was a cancellation (a sailing holiday he booked) I was a bit shocked- I thought, your daughter is having your grandchild and needs your help and you want to go on a bloody holiday! But maybe I just expect hope for too much! She will help me but only EVER on her terms.
My mum never had help from her mum when she had us (due to geographic distance) and I think she assumes women should just 'cope' and not fuss like she did. BUT she had a whole bloody week in hospital to get to grips with feeding, have a rest (whilst they took baby away at night so mums could sleep) and then come home. These days we're chucked out as soon as possible sleep deprived, struggling to BF and cope and expected just to get on with it!
Sorry, moan over but I just know how you feel and really think support is so important in those early weeks. I hope one of your friends/family realize and help you out as much as possible
