All babies run at their own pace. Some do things early others don't do things until they are much older.

So I will only comment by what happened with us and lil miss...
Lifting thier heads? Lil miss could support and lift her head from birth.
Teething? 4 months she got her first tooth but was niggly from 2 months but that was really early.
sleeping for more than an hour
?(im breast feeding) Lil miss didn't start sleeping for more than an hour till gone 12 weeks and only at night if she was co sleeping. Oh and it wasn't consistent. She started sleeping through from around 9 months.
smiling? Lil miss was around 3 weeks old.
having established routines with nap times and feeds? I had a "routine" from day one. I have Tia so there was already a routine... All I did was to get lil miss up at 8am every morning without fail and start the bedtime routine at 8pm every night. She eventually just fell into a general routine, which changes every few months depending on her development. Feeds have never EVER been consistent...although she would get hungry around the same time.
seeing close people (mum, dad ect) and recognising them? I have absolutely no idea... She seemed to recognise me from birth and DH within a few days following birth...but she didn't really start showing happiness at our presence until she was around 6 weeks old.
At the moment you are giving EVERYTHING to your LO especially as you are bfing and your baby is giving you nothing in return. But when they do.. you realise that it was completely worth it and it gives you the get go to keep going.. but at the moment its slightly demoralising being boob all the time and no one appreciating you for it.... but they will
