How many hrs/day is your baby sleeping?

My baby is 2.5 months and EBF. My baby eats every 3-4 hours during the day and sleeps for 15-16 hours total. The past couple days my baby has slept for 16-17 hours. It’s 9pm and we’re at 17 hours already of sleep today and I’m getting worried something may be wrong. She’s acting normal though. She has already had her 2 month growth spurt and her leap occurred 2 weeks ago (according to the wonder weeks app and her increased fussiness correlated with the fussy phase of the app)
