how long does your baby feed

the last day or 2 Megan has only been feeding for about 5-10 minutes. She is having plenty of wet nappies about 5
so far today so she must be getting enough from me.

When Sam was around 6 weeks she started feeding for around 5 minutes max. She always got plenty though.
Sounds like you probably have a nice fast let down

When Ella was that age she would take about 30- 45 mins for a feed (man, I don't miss how long those middle of the night feeds would take).

Now she feeds 5 mins per side.

My second baby feed very fast, about 5 mins per side.

As long as she has wet nappies I wouldn't worry. Like the others sounds like you might have a excellent let down reflex.

When she starts to get a little bigger and a little hungrier you might find that she increases the amount of time on the breast to stimulate more milk production.
