My baby is 10 weeks now and he is still waking up every two hours or lesser for milk ( shorter in the day time ) . He drinks about 80- 100 ml each time . Is it too much ? How can I lengthen the feeding time and let him sleep more esp at night ?

my baby also 10 weeks old. she drinks abt 90 - 120ml every 3 hours. at night she sleeps longer. we feed her about 120-130ml for her last feed and she will sleep for about 5-6 hours.
