I have an almost 8month old. But the "newborn" tag you are talking about wears off around 4months. I know that i felt exactly the same as you are now, not knowing what the feeding routine was but when the CAFS woman came to my house at the check up at home. She had gotten me to write a list of his feeds and how long he is awake for for about 3days and 3nights before she came so she could tell me if it was a "normal" routine. (WHATS NORMAL!!!) she said it was fairly normal, but to me it was all over the place. It probably wasnt until Kayden was 2months old that i had got used to his cries and what he wanted. So dont panic, different cries mean different things and you WILL figure it out soon enough!
I dont know how many feeds you are giving her a day, but i know i was on 6 up until about 4-5months and then it started dropping to 5, then 4 probably each month. Now he is almost 8months and has started doing the 3 bottles a day (have just finished weaning him) and these are for breakfast, lunch & tea.
Settling, is hard. Does she have a dummy? I stayed strong on not giving Kayden a dummy up until where your at now, because i couldnt stand the constant screaming. I had heard through a friend that if you had a c-section the baby doesnt have the coating on the lungs at first as it would if it passed through the vagina so Yoghurt is Excellent for this when they are a couple of weeks old. But it has to be PLAIN, NATURAL yoghurt, not the sweetend ones. Instead of putting the yoghurt on a teaspoon i started putting it on his dummy and letting him go to sleep with it. It worked a treat!!!! but it is hard to get them off of it when you dont want to give them the dummy any more! so, a bit of time with a dummy (maybe not yoghurt-depends on how desperate you are) might work for you.
Sometimes, if you dont catch your baby on the first yawn or tired signs it can make them OVER tired. This is worse because then when they do go down for a sleep it is harder to get them to go to sleep. so watch out for the signs.
One more thing - play time is what ever you want it to be. If you are exhausted and are wanting a rest. Put her on her back under a play gym for something to look at. The rocker-bouncer things are good if you have things to do. (once a day) and other things that the ladies above have advised, looking out of windows, playing with your face. Poking your tounge out, flicking your eyes she will soon learn to do, by copying! and they are the cutest little things when they pic something up from you. A bit of tummy time at this stage should be started, if she doesnt like it - try for the 10seconds, then put her back on her back or give her a cuddle. The next day go for 20 seconds and so on. Soon it will get up to a minute and this is a development for her also. I found the best toy to keep kayden on the floor was a Mirror toy which was a "sassy" brand, it has a few toys around it bright and colourful standing in like a triangle frame shape and you can place it on the floor infront of bubs. THEY LOVE looking at them selves. This would keep him on the floor for a while. Even now he still uses it playing peek a boo with him self!
Stay strong babe, i know the first few weeks are pretty bad getting labeled the "newbie" but believe me as a first time mum i know exactly what you mean by not knowing what your baby is crying about. visit mumsgroup.tk where a whole heap of new mums are! there is lots of things for you to read up on, when you have time!
Hope this is some help... and i didnt dribble on for too long! haha... looks like i did... sorry!
