I don’t understand my baby

Title speaks for itself really! I am always seeing mums on here talking about their baby’s eating a good amount and being on a very loose schedule with feeding times. I don’t have any of that with my daughter 😢

She’ll be 8 weeks tomorrow, is my first baby, and I haven’t got a bloody clue! She eats anywhere between 2 and 4.5oz of milk and has it anywhere between 2.5 and 5 hour gaps! There’s nothing set in stone. Her bedtime has been chaotic the past few days cause even though she is tired she won’t sleep! Maybe I let her nap too long in the day? Who knows, lord knows I don’t! I’m a single mum, so I’m doing all this alone and feeling like I’m failing at every step!
