I have a 6 week old baby born 7lb 7oz. He is now 11lb 2oz so I know he is gaining well. I was wondering though if it is normal to have more than one let down per breast per feed? After he latches on he sucks for a minute or so and I experience a let down. He then sucks vigorously until getting one suck per swallow for about one minute and then slows down to a few sucks per swallow. This lasts about 2-3 minutes. He then lightly sucks without swallowing for several minutes until I have another let down. This repeats about 2-3 times per breast per feed. In a 20 minute period on one breast he is really only getting milk about half the time. It takes about 40 minutes to feed him and then will want to eat again in an hour & 1/2 to 2hours. Is this normal?
