Baby J is 8 days old and has mostly been satisfied/ asleep after nursing on one side. Now that I'm less engorged I wonder if he needs the second side. He never really takes himself off the first side though - just sort of falls asleep but I can still hear swallowing. How do I know when to switch?

If I can still express a little milk from the first side after taking him off does that means I shoulf have just let him continue on that side? I feel like a FTM all over again with this stuff!
