Haroula, don't stress too much hun, my health nurse told me that Madeleine should be drinking 180mL per feed now as she is 6.3kgs (based on 5 feeds within 24 hours [150mL per kilo]) but she has 180mL sometimes and other times she'll have 150mL and rarely only 100mL!! They go up and down a bit.

Sometimes, when Madeleine has not fed for 4 hours and she only has 100mL and stops, I burp her, change her nappy and then sit back down and try again. Most of the time, she'll then drink the extra 80mL!

Do you record her feeds? I do and find it really helpful.
