Love his family but..

I love my husband's side of the family, I've never had problems with them until now.. I'll try to make this short, I just need to vent and know if I'm overreacting. Since our son has been born they are constantly calling or texting me, getting upset with me or informing my husband I'm not sending enough pictures of our son. (I send them weekly.) Plus they have been making plans with us every single weekend since he's been born and plans during the week day while my husband is at work. Even if we set a time up they are calling us an hour before to make sure we are still coming and will call us after we get home. Just today while at his grandma's she has made four plans for us in the next two weeks. I talked to my husband about it and he just keeps saying well it's the first baby that's been born in a long time.. That's great and I love how much they are excited and love him but I need some space and don't want to talk or see people for quite some time.
