I just had a newborn a little over 2 weeks ago and a few weeks before he was born my husband's grandparents arrived from another state to stay for the entire summer. Since the baby was born c-sec I've been in the babys room mostly with the door closed just healing and bonding with my newborn. My husbands grandparents don't think it's healthy and complain about it but since they've arrived I've felt cramped and not comfortable in our environment like before, obviously. I have taken the baby outside for a little sun and air otherwise. And I love his grandparents but besides them being 86 and 90, my husband's grandmother just had a stroke just 3 months ago and they both kind of drive us crazy with their senescence and well meaningful parenting "advice." In essence, IIN to lock myself in the nursery healing and bonding with my newborn while my babys great grandparents spend the summer driving us crazy??

Will they be offended if you ask them to leave?
I couldn't handle it, I'd lock myself in the nursery too.
If so, big mistake.
People adapt to their surroundings quickly. As above, the bonding time at the beginning is very important. Yes call on help when you need it, but fulltime? Day and night? Have you got a physical or mental issue? If not, then it should just be you and your husband, even if your husband works long hours. That's all you need.
You are an adult, a fulltime provider (including love) and a parent now (if you have previous children, they can even help) You ARE able to do this. People in 3rd world countries do it with little food and poor housing, lack of water etc, they have no time for psychological parental issues. Time to grow up and be that parent. The grand parents will understand (I'm positive) move them out in this special immediate family time. Unless its all too much for you?
Take some time off,let them help you..Although it's normal that you feel so, solution is quite easy
