Income and cutting costs help!!

Hi! Im from the U.S. and We are going down to one income soon. I have two kids ages 3 and 11 month. What are some life hacks to cut cost on items and make this possible and still put money away for a house in the near future. This momma is stressing. Is there any jobs a momma like this can do at home with two crazy kids. Ive tried mlm and to babysit but most parents want you to go to their house or have no kids of your own while watching theirs. Please no rude comments and we only have this choice for e to become a SAHM. TIA!!
