Oops forgot to add that my Mom did stay with us for 2.5 weeks after Isla was born and it was honestly amazing, (I'm going to try and get her to stay for longer next time).
She helped look after Isla so I could nap during the day, cleaned the house, got groceries and made dinner for us. It was amazing to have all of the support and really helped DH and I at the beginning, especially when we were also dealing with tons of visitors and my raging hormones.
I have a very close relationship with my Mom though and was comfortable bfing in front of her, etc, if you don't have that kind of relationship it might make things awkward...
Having a newborn is tough though so extra help might be nice, again it depends on if you think your Mom actually be helpful though...
