I can't stand my inlaws

For the past 4 months I have been a SAHM. For a couple of years before this I ran an in home daycare. Before that I worked part time to try to get in as much time with my kids as possible. Before my kids were born I worked full time and paid the majority of mine and my husband's bills. My husband and I made a mutual decision that it was best for our family for me to stay home and take care of our kids until they are all in school full time. We are able to afford this without any assistance. Since I became a SAHM I have gotten multiple comments from my inlaws about how my kids are unsocialized and need to be in daycare. They have also told me many times that I need to get a job and my husband shouldn't be the only one bringing in an income. I am getting so sick of this and tired of ignoring it to try to keep peace. I'm going to blow up soon. What we do with our family is none of their business! This was a decision that my husband and I made TOGETHER I am NOT taking advantage of him, he wants me to stay home! And my kids have been socialized their entire lives. They still have playdates with their best friends. What would you all do? Is it time to tell them to fuck off or should I keep ignoring them? Or am I in the wrong completely?
