Am I in the wrong?

I am currently almost 33wks pregnant and my son will be one year old in 6 days. My in laws only live two minutes up the street. My morning routine consists of waking up at 6am with the little guy, then going downstairs by 7am and eating breakfast by 8am. 9:00-9:30 he’s ready for a nap and so am I.

So we go for a nap.

Sometimes he sleeps for 2 hours. Sometimes it’s an hour. Sometimes I can sleep sometimes I can’t lol. But my MIL calls at 9 am to ask to come see him. Usually I don’t answer because we are winding down. Then 10am rolls around and FIL decides to knock on the door. This irritates me to no end. I tell them time and time again that unless they want to be at the house between 7-9 mornings don’t work.

After a nap then we get ready for the day. So between 11:30-12:15 we are getting a shower and a bath and dress and then finally around 12:30 it’s lunch time. So I ask them if they can come down after 1pm. Why is this so hard to comprehend. This always gets me irritated and grumpy.

Am I wrong for this? We literally have had this schedule for months. We do the same thing day in and day out.

They say/think I’m ignoring them and don’t want them to see their grandson. It’s not that. It’s the timing. It’s not always convenient. Sometimes I don’t want company.

What do you guys think?
