5 month old wakes to feed constantly

My daughter is 5 months old and at night she wakes every 2-3 hours to eat, just like when she was a newborn! She’s an easy baby otherwise, eats a lot during the day and only cries if she needs or wants something, smiles all the time and loves being with people. She has no health issues and is at a healthy weight and height for her age, in fact she is in the 90th percentile for weight. Is this just a phase or should I try to push more food on her during the day so she will sleep through the night? I need more sleep!!! Oh man do I just want at least four or five hours in a row. What is this? She used to sleep for longer stretches but for the past week or so she’s been doing this.
