You're a stay at home mom because you're lazy

Im 25 years old, going on 26. For the past 3 and a half years ive been fortunate to be a stay at home mom for my first child and will be doing the same for my second, third etc. My hubby is medically retired from the army and we are very financially stabled. Im so tired of hearing from a few people including my mom how im lazy and need to get my life together because i shouldn't ever depend on a man. I had a great job before my son was diagnosed with autism which required in home theraphy 4 days a week and just last year he started school for only 3 hours a day. Why do ppl think being a stay at home mom is being lazy???? Like i literally get no break!!! Only when my son is in school,and technically i take that time to run errands, clean, laundry, cook, you name it! I work more at home than my previous job but im not complaining. I enjoy seeing my son grow up and hubby and i are working on starting up a business so i can work from home. There's nothing else in life ill rather do. No matter how much money a job is willing to pay, this is how i want my life to be. Unless we go through hard moments and money is needed, then ofcourse i will 100% figure it out but why are others concerned with what i bring to the table when WE aint even concerned about it??? What do you think about stay at home moms?
