Eating habbits @16 months

Hey Moms! I need some advice, My LO just started daycare and isn't eating anything they are offering aside from her bottle. She has always kind of been a picky eater and usually only eats a few bites of whatever i make throughout the day when she does get hungry, but again, that's throughout the day &mostly only when she asks for "papa" (food). My question is, what can I do to help her get on a better eating schedule and help to assist her in actually wanting to sit and eat a whole plate of food. I'm kind of worried she won't eat at all aside maybe snacks at daycare. When she's come home the past few days she's been really tired and goes straight to sleep once we get home. i've been able to sneak her a bottle while she sleeps but i don't want her not eating at all! Please anyone, any advice would be awesome! i'm a first time single mama &dnt have a village here in GA. Tryina figure this out on my own w a ton of google isn't the same as speaking w experienced moms.
