I'm planning family visits for May after out first LO is born. With my DH being disabled, my mom will be staying for a week after delivery to help us out.

My SIL offered to come and help too, so we are trying to coordinate dates now since I'll be induced at 39 weeks. I'd like to have her come right after my mom leaves. She just emailed me today saying that she'd like to bring her toddler (about 20 months) if possible because she doesn't want to be away from her too long.

I'd love to say yes, because we love our nieces and they live all the way on the west coast, but I'm worried. I'm not super worried about germs and I'd be tempted to say that it's fine as long as my niece is vaccinated, but....

I'm also worried that having the toddler around will be too chaotic for us in the early days of having a newborn. Our house is small and we only have 2 bedrooms. The 2nd bedroom is the baby's room. Although he will sleep in our room, I'll need access to the changing table in his room.

What would you do in this situation? Let SIL bring the toddler? Tell her it's too much and risk that she may not be able to come? Something else?
