Desperate for some advice please ladies. My 2 week old DD has not settled into any feeding routine as yet and I have been bf on demand. My supply usually seems to be plenty although she has just been through a growth spurt which was exhausting - feeding CONSTANTLY. She's got a bit of a cold - very snuffly and sometimes finding it very difficult to breathe - because of this since yesterday morning she's only been able to latch on for 5 mins at a time and I was feeding every half an hour more or less. Was so exhausted last night and she didn't seem to be latching on at all and had used all my expressed milk that in desperation we tried to top her up with some formula. She didn't like it much but took about 100ml. Wouldn't settle for another hour or so and then finally fell asleep in my arms about midnight. She then has slept almost constantly which has made me really worried that I've done something wrong by giving her the formula. I managed to wake her about 5 and she latched on for 5 mins but went straight back to sleep. We couldn't get her to wake until we gave her a bath which also seemed to help her breathing which was becoming scaring laboured. Had a 15 min feed about half 7 and now straight back asleep. Is this ok or should I be worried? She hardly seemed to sleep yesterday so she must be very tired but I'm worried that she's not getting enough food if she's not waking up for feeds. Sorry for long rambling one but am terrified I've done something really wrong!
