I NEED YOUR HELP PLEASE!!!!!

Savannah
Please help I can't go back to sleep unless I know it's okay. My baby is over a month old (5weeks) and it's 2 am... I woke up because I last fed her around 8pm and was worried. I usually feed her every 3 hours during the night. Is this okay? Should I wake her or let her sleep?? It's been 6 hours and she hasn't eaten or had a diaper change
