I Have a question ?

Okay so i work mon-wed 4pm-12am and sat-sun 8am-4pm & my husband works mon-thus 4pm-12am and sunday 4pm-12am we moved & the only family i have out here is my mom and since the virus is going on i cant put my child in daycare .. and i don’t trust anyone else with my child .. me and my bf have strict rules for my child and have a schedule when he eats breakfast and lunch and dinner and when he takes naps .. so when he eats breakfast and than lunch and take a nap we drop him off when he wakes up because thats the time we get ready and go to work at my moms i let her know everyday he has a snack in his bag until you cook dinner ... which his dinner time is 6:30 because his bedtime is at 8:00 or 8:30 .. when i call her at 5 and ask her what he ate she always says chips candy cereal ... just junk ! When i told her not to give him junk anymore he’s only 2 he shouldnt be eating 3 meals when he goes over there i dont feel like he needs all that he drinks milk in the morning and drinks water the whole day and for dinner i give him alittle juice and all she gives is milk and juice everything i tell her NOT to do it seem like she always does the opposite when i pick him up at night he is always up or when i call at 9 he is always up when i told her he should be in his pjs and sleep by than because when i pick him up we don’t want him up at 12am all night i want to say something and i don’t wanna bring him over there no more if she doesn’t respect what i’m doing with my child everything we teach him its like he forgetting because shes not doing it at her house but she is also the only person i have to watch him right now ... what would y’all do if y’all was in this situation ?
