Ok well I followed Manny's tips along with my sister's very similar ones and basically have been sticking toca routine-and gas reduced (so actually the signs of gas may also have been frustration/boredom/tiredness) as was grunting/crying etc and we had an 8 hour stretch last night! Amazing!
So when she wakes in morning it's curtains open, downstairs to be fed, noise around her, change nappy. Nap on sofa with same noises (although I turn tv on lower and put hoover noises on from app which sends her off to sleep). I then get ready for day and get her day clothes ready. When she wakes about 11ish I feed her, wash her and change into day clothes then finish feeding her-then we go out! Fresh air, noise, you name it for at least an hour. Yesterday we went to watch a rugby match and she slept whole time in sling with me! Then if awake I talk/play with her minimally ie cuddles/feet kissing/carry her around etc. Then 6-7pm a bath which she now loves, then feed then sleep! Burp her about 3 times per feed. Sometimes she can be down for 8, sometimes a bit later like half 9. Little Nia was sick last night as soon as I put her down (rare) bless her-soaked her! So I had to wash her in sink and change bedding and give her a top up! Then she slept for 8 hours! I also give her an ounce of formula-IF I think she isn't getting enough from me. But I may have been wrong with that last night as she was sick! She was tugging away and pulling at my nipple!
