Nursing babies

My son was born April 11th 2019. He is breastfeed and gets bottles when I'm at work.

He is almost 9 months old and still takes 25-30 minutes to eat. Oh and he still eats every 90 minutes most times. Unless

I can distract him with things to play with he will go longer. He is being introduced to solid foods. When he gets a bottle he eats about 5 oz and takes about 20 minutes.

I kinda wonder if it is me, because his older sister would take forever too. I also pump every 3 hours during the day for 10 minutes each session and I get anywhere from 2-5 ounces total. Usually more out of the right than left. He is a small baby, only 15 lbs and 8 oz. Though my husband and I aren't tall people either.

I just thought they got faster as they got older. It's just frustrating.
