During the night 7 week old DD had a feed at around 4am but then seemed to bring all of it back up. She slept from 7-10 and I woke her for a change & feed. She fed for 20 minutes and has now bought all of it back up again - she's soaked through her bib, a muslin and my t shirt. She's had a cold for a while now but it hasn't affected her eating. She's having plenty of wet nappies and seems fine in herself, if a little sleepy. Do you think there's anything that needs addressing or does this sound normal?
