Baby eating too much?

My daughter is 4 months and she eats between 5-6oz (150ml-180ml) approximately 5 times per day, plus she drinks around 7oz (210ml) right before bed. For whatever reason she’s always starving right before bed, but then she sleeps 12+ hours without eating anything. She’s formula fed and I’m always extremely aware of her cues when she’s done eating, so I never push her to drink more than she wants. She’s currently in the 46th % for weight and the 75th % for height, but she definitely has rolls on her thighs, and a very round face.

Last night we were FaceTiming with my MIL and she made a comment about our daughters weight and that we need to be careful about feeding her too much because right now is when they build fat cells that never go away. I’m very tall and thin, and my husband is tall and average weight, so I never really thought about my daughters weight. Should I be concerned? Is there something I should be doing differently as far as her feeding schedule, like maybe feeding smaller portions more often?
