Ihss and ssi

Hey yall I wanted to know is anyone who’s receiving ihss hours / PS hours for their child also receiving ssi for them ? I applied for ssi before I did the PS . He just got approved for PS first and we’re still waiting on ssi decision . but I’m wondering , will him getting PS make him ineligible for ssi ? 🤔 Cus I know for a fact they’re going to cut my food stamps and cash aid off the county when I start getting paid as his provider . TIA .
