First time Mum here! My DD is nearly 5 weeks old, and in the last week or so has started to posset (sp?) what looks like significant amounts.
She doesn't seem bothered by it, but she is already quite a thin baby (75pc for length but only about 15-20pc for weight) and not quite keeping up with her centile (she started at about 25pc). We don't have the most brilliant latch (though better than it was - Nipples are healing and pain not too bad and only when I first put her on). So I worry if she's having enough. She also gives feeding cues a lot (even e.g. when she's been on an hour, drained boobs from hard to soft, and had a 10min sleep, she'll be straight back to tongues. I've started enforcing a 1 hour gap if she's been on an hour as my nipples were in tatters, though I feel really guilty about it in case I'm compromising her weight gain 
)
She seems to posset particularly after she's been v hungry. So e.g. most mornings around 7-8 she would drain one boob, and the last couple of days I've expressed the other for an extra evening feed (she cluster feeds in the evening and I never feel I have enough to satisfy her, whereas in the mornings my boobs seem to refill fast). But today she drained both, but then appears to have deposited half if it into her clothes and various muslins. Quite a lot came out even when I was holding her almost upright.
Any ideas for ways to make sure she hangs on to as much as possible?
