Me too. My baby is 1.5 month old. Every time I need to feed her for 40-60 min. It seems better these few days. There are sometimes she eats for about 30-35 min. Usually she need to eat 2.5 - 3.5 hr.
Luckily, she can wait to eat around 4a.m. after I feed her around 11:00p.m. Then she will eat around 7:00a.m. Usually I lay on the bed to feed her. I will sleep during feeding. Hence, it takes longer time to feed her, around 1-2 hour.
I'm not sure if there is anything wrong, e.g. she cannot properly drink my milk. Anyway, she uses around 6 nappies per day and her weight increases. I think it is still fine.
My friend said that the situation will improve when she is 3-4 month old. Does there any mum have any idea?
