My baby is 3.5 months old, and EBF. She's 12 lbs 4oz as of yesterday. She's gaining weight very slowly. She went about a month without gaining anything at all! She's got chub, she's alert, happy, sleeps well, hardly ever fusses, has plenty of pees and poos, etc. So I didn't realize she wasn't gaining until a week or so ago.
When I nurse her she nurses for about 7 minutes and then she's done. At night she'll dreamfeed for longer, but I'm worried that she's not getting enough hindmilk during the day. What can I do to encourage her to nurse longer?
