I have BF 3 ds' and am still BF ds3 who is now 10 months old.
I have been very lucky and found it very easy. But I do think it helps if your partner is supportive.
In the very early days I found that you feel like you are tied to the sofa feeding baby so my dh always set me up a little tray with a jug of water and some snacks wherever I found it was most comfortable to feed, before he went to work.
Reading on a smartphone/ipad is great entertainment, or do it in front of the tv. DS1 BF for 45 mins every 2 hours for the first few weeks so boy did I need entertaining.
Just go with the flow and feed on demand, that way you will have plentiful supply. any attempt at "routines" for BF will limit your supply and is more likely to you ending up having to bottle feed.
Don't buy expensive feeding tops - I found loose tops much easier. I just pull them up and as they are loose they drape round baby and combined with baby just covers everything up. I got so adept at this that when DS3 was 6 weeks old, we took the whole family to legoland and I was even able to walk up a hill, pushing a buggy with DS2 in it, whilst cradling ds3 in one arm, feeding him at the same time.... Needs must when you have 3!!! I would hasten to add that I am a discrete person and do not like to flaunt breastfeeding at all!
Mostly people didn't even realise I am feeding my babies when I am feeding them - they think I am just cuddling a snoozing child!
On the other hand, those new type cover ups which are like aprons or capes that you are supposed to wear over your baby to cover you up just scream "I am breastfeeding" to the whole world and are not subtle at all!
I wish I had known with DS1 just how nice it is to BF lying down in bed. Lunchtime naps and for the first few months (whilst I co-slept) I always fed lying down, that way we both just fell asleep and it led to my children being great lunch time nappers. I have had no problem at 6 months moving my children into sleeping in their own beds....
Drink loads and loads of fluids, and eat lots! don't even attempt to diet if you want to BF - you need lots of energy.
Just because they get teeth does not mean you have to stop. I have fed all mine with a full set. And mine got first teeth at 3 months old. They may go through a few days of nipping a bit when new teeth come through but they soon stop.
hope you are successful!
