Increasing feedings?

My daughter is 2 months old. She currently eats 2 oz every 2 hours (breastmilk) while at daycare and nurses directly from the fountain while she's with me. She's been hungrier lately. Wondering if I up it to 3oz should I continue every two hours or stretch it out? I don't want to send less bottles to daycare and have her starve! She's gaining weight just fine; lil chunker. 😁
