Breastfeeding mamas

Coco

So my baby still nurses every 2-3 hours during the day, but only like 4-5 minutes 🤔... should he be nursing less? Like every 4 hours? And, he wakes at 2 am and resumes to comfort feed , every two hours 🤨.. but only like 3-4 minutes lol 😫 should I be doing something different? Maybe feed less frequently ? Or is this normal ?? Tomorrow is his 9 month check up, curious to see how much he weighs
