Hi Gilby
First of all I agree with annoyingdevil re the routine - I know it's early days, but I do believe that my ds was also overtired as he was screaming so much of the time. I only turned a corner when I started to roughly follow, dare I say it, dare I.....(whispers) The Contented Little Baby by The One We Do Not Speak Of. It was when ds was 5 weeks old and I had had enough with the breastfeeding as he would only be quiet when latched on and I could not put him down. I reluctantly started fully bottle feeding on Aptimil (we had given him a bottle at night up to this point), and I was able to put him down to sleep without him waking up!
However the contentedness didn't last long as he was soon back to his screaming all night and I ended up at the out of hours doctor at 11pm, who prescribed Gaviscon Infant. It seemed to do the trick, however at my 6 week check with the doctor (at 8 weeks bizarrely), I broke down and told her about his constant crying and she suggested cow's milk protein intolerance and put him on Nutramigen 1. It was like an instant improvement and within days he was sleeping better in the day for about 2.5 hours after lunch which was just bliss. Also was better at night as we could put him down and then come downstairs for dinner, rather than having a relay of one of us eating while the other held the crying baby. He still suffered the reflux quite badly, but the Gaviscon did help until he got a bit older when it stopped working for keeping the milk down. However the vomiting was no longer causing problems for him by this stage (just me with a stained carpet!) He still has the reflux now, but it is minimal and I am told they grow out of it around age 1 which he is next week.
I also bought a rather expensive baby swing with a mobile and soothing music, but it was a lifesaver as it rocked him to sleep in the day, and was a reclined seat, rather than flat, so great for the reflux.
And I was lucky to have a lovely health visitor give me a home visit assessment, as I think I was verging on going into deep post natal depression.
Looking back now, I think that my ds had reflux and possibly colic to start off with, and that was excacerbated(sp) by us giving him a night time bottle, and then further when I went on to full bottle feeding. In addition to this, I believe he was also completely shattered from the crying and lack of sleep.
I do realise that newborns cry, and are unsettled at times, but I honestly thought that this normal and was just how babies are, and it is only now, after speaking to many people with babies and children, that I realise that my ds was very unsettled, and for a good reason. That's why I say don't suffer in silence.
I also tried cranial osteopathy and baby massage classes, both of which were very good.
