Crikey Olivo - what a birth, you poor things. In that case, a trip to see the Osteo gets my vote. Friends of mine who had similar experiences tried this and were basically told that their baby was probably having bad headaches as a result and/or digestion problems. These things will settle down in due course but you may not want to wait. My gut instinct, if this has something to do with your problems, is (while you are waiting for an appt.) to make the house as calm and quiet as possible ALL DAY. Avoid visitors, turn off the TV, keep voices low, just have soft must (Classic FM!) in the background and keep bright lights to a minimum - just imagine how you'd feel if you had a migraine? Thats just my opinion - no expert.
..and you say you're breastfeeding. Well done! Can't believe you even started let alone managed to carry on with everything you've been going through. I bet you are doubting yourself as a Mum at the moment - DON'T - there's nothing obvious that you are doing wrong, quite the opposite - you are doing SO much right by breast feeding. Try to take some comfort in that.
..back to my comment the other day when I said to ensure your DD was well fed. Breast fed babies can fool you quite easily to start off with. Breast milk is like a drug, baby takes a hit and zonks out fooling you into thinking they are full...then they sober up 20 mins later, remember they are still hungry, start crying and you are thinking, "..but I just fed you?!?!?". The trick is to try to keep them "with it" until they really are full. Stroke their hair or face maybe put them over your sholder and wind them...just to stir them, and then put them back to the same breast again. If they drift off again, repeat the exercise but then maybe try the other breast, stiring them again if needs be. Only then would I be happy they really were full. I'm not suggesting you irritate baby..just gently stir them. Another problem can sometimes be that you think they have finished and then next feed (even if its 30 mins later) you put them to the other breast. If first feed was pretty short then there could be a problem with them getting too much foremilk, this is empty calories and will mean they won't sleep well and maybe even have a tummy ache (in my experience). No one should suggest a time limit for each breast, this will vary for each person. Try to feed on one side until you think its empty or until you think baby is telling you it is - can't tell you exactly what to look out for here, I didn't work this out until my DD was alot older! I think she just used to go on and come off again quite quickly, I'd switch sides and off she'd go. I know people who only ever feed on one side so if in doubt, don't switch.
You could find this extra faffing around lengthens feeds - anything up to an hour in these early days. Thats normal. Think of it as Mother Natures way of forcing you to sit down and rest, just go with it, it won't last forever.
Another thing to concentrate on is winding your baby. Make sure you are doing it correctly (I was told make firm, circular strokes on the back in a clock wise direction). Again, get help on what to look out for - if baby lifts her legs up when she's lying down crying then that could be a sign , also if she crys as soon as she's put down - although that could also be because she was having a lovely cuddle. Speak to your HV if in doubt and ask for tips on baby massage which can help. Baby massage might also generally calm her down and also give you two some nice quality time together in between the screaming.
....and I know this contradicts what I said earlier, but sometimes a bit of white noise helps (mimics the womb). I've recently had a CD of a cat purring on all night to calm my DD - not sure it helped her but I slept really well
Sorry to write such a war and peace - unfortunately I have too good a memory and can quite clearly remember those first few mental weeks. Fingers crossed for a better day tomorrow x
