With my dd I would have been lost with out my Mum. My daughter I swear didnt sleep for the 1st 5 days home fomr hospital, my Mum was there to help I to was breast feeding but being able to catch some sleep and have someone else make you dinners and clean up is an amazing help. This time around my Mum will be taking a week off, she wont be staying with me this time as I am married to a wonderful man whom is anxious to be a daddy , my dd is 9 and he's never done the baby thing
but she will be here everyday during the day that help alone is a great help and will make it so much easier for you. My mother and I dont get along period but the baby seems to bring out the best in both of us and we kinda have agreed to disgree lol Good luck with your Mum I hope it all works out how you want it to, but I think having her come help you for a week isnt to bad of an idea.
