My DS is 14 wks, so tips to date:
BF can HURT; I'm bloody minded so persisted and by week 3 it was better. Best tip was to count to 10 or 20 each time DS latched on and pain should go away, if it didn't then latch was not correct (ie nipple not pointing to roof of baby's mouth). Watch This Morning when BF, at least Philip and Fern made me smile... Now at wk 14 no pain at all, except for when lazy and done bad latch or if DS feeding for Britain. If DC does feed for Britain, it is OK to swap breasts after 15 mins...
Tummy time: DS hates it too, best trick so far is for me to sit on floor with legs outstretched, DS face down across my thighs, then 'walk' my legs to bounce him on thighs while singing a made-up song. That, followed by rolling him along my legs (sounds bizarre but he loves it) works a treat. Then follow it with him lying on his back on floor and gently bouncing his legs like when changing nappy - loads of wind released! However re tummy time, my HV was reassuring and said his muscles will strengthen in time anyway. If you are worried about flat head, you can see Plagio UK site for suggested products, we got Goi Goi pillow, seems to be working.
Colds: DS in full flood at mo. A saline nasal spray helps thin mucus (I'm using Weleda, but think Doc can prescribe) - when baby has cold, more burps get trapped by mucus so they can have more wind too. One midwife suggested putting vaseline either side of nose bridge, think this is to help block pores so breathing through nose dries out mucus. Sneezing is baby's way of clearing mucus - try to keep them upright so that it drains.
See Kelly Mum article!
Cries: Thanks v much for tip re staring, Columbia - had wondered why DS was fixing gimlet eye on me. I've been waiting for the 'cough cry' as described by The Baby Whisperer. This book v useful for other body language/cries.
Sleep: The No Cry Sleep Solution book looks good - been lent to me by HV so must be OK! Also re 'sleeping through night', if BF, baby not so 'full' as bottle fed babies so won't sleep through night as soon. And according to NCSS book, 'sleeping through night' actually means for a stretch of 5 hours. So DS technically sleeping through night already, most nights! Shame his stretch starts at 8pm...
Other useful books: Infant Massage (Vimala McClure) gives enough info for you to do massage if you can't get to a class.
I'm sure there's loads of other things, but this post already long enough...
