Mom hair styles??!!

Alright ladies, I’m on maternity leave right now but I’m an assistant manager as a fast food restaurant and I’m a mom of a : year old and 1 month old. I have long hair, down to my bra strap. I don’t want to cut my hair because I don’t look good with short hair, but with a new born and the every few hour schedule and opposite work schedule as my husband, I don’t have a lot of energy to do my hair. My hair is wavy/straight and thick. What are good and easy ways to get over night curls or really just any cute easy hair styles that will help me not look too much like an exhausted mess 😂 thank you ladies!!
