In summary:
- Osteopathy
- Keep her stimulated and busy during the day
- Let her sleep when she wants to - no 'scheduled' naps.
Your baby's only 'language' right now to express worry or hunger or whatever, is crying. Imagine if you were alone on an alien planet and were hungry or thirsty or in pain or scared. No matter how you tried to convey this to the inhabitants, the message did not get through to them. And if their responses were to hit you or scream at you or ignore you, how would that make you feel? Sad, depressed, more anxious, and desolate? Certainly not loved or liked or respected. A frightening scenario.
So I'm sorry, but to leave a baby to cry, is not a good and kind thing to do. Comforting and hugging and kissing are what the babies need and so learns that there is someone who cares and is there to love and support them! I remember in the first months wishing I had a sound-proof rubbish bin that I could just pop my baby in for a short while so I could get some sleep, but obviously did not.
I did lots of walking outdoors, going to the local park where she was stimulated by contact with other babies and animals and people and flowers, and grass to crawl on, and massage, and lots of skin-to skin contact, and playing in the bath, and 'reading' picture books, and talking, singing and dancing, and more importantly, never stuck to a rigid schedule of naps, and bedtimes, and meal times, etc. I did nurse on demand though. Started introducing solids from 7 months.
Hang in there.
Also, whenever you go past a mirror, look at yourself and smile - this releases endorphins and calms you. Sounds silly, but it is effective.
