I'm breastfeeding a baby who is 21months old.
And have been doing since the very first day she was alive.
The thing is, when you are pregnant, you have so many worries and concerns, and questions and what-ifs.
when your baby arrives, you'll have so many people telling you what you should be doing and how you should be doing it.
they'll dictate to you what the baby should wear, how often they should feed, when they should sleep, what they should be doing.
but you know what (apart from any developmental problems), it really doesn't matter
the best advice I can give you is that your lifewill be turned upside down. you won't know what's hit you.
But, you are in charge of this tiny weeny thing, it wants and needs you for everything. It doesn't understand the clock, or routine, or even day from night in the early stages. It doesn't understand rules or anything - all it knows is it needs something and it's you who can provide it.
So, don't listen to the rules, don't do anything that anyone else tells you - listen to your baby. If the baby is hungry, feed it (and yes, sometimes that can be every hour for days on end! in the early days (and during growth spurts), if it's wet or soiled, change it. If it's crying, cuddle it (or all the other things that you need to check) but the biggest thing is go with it all stages will pass, and you'll both find your own best way.
FWIW, I really love the fact that I breastfeed DD, and I feel like I'm doing something really special that no one else can do.
And I don't care how much time it takes. And whenever I'm stressed, the only way I can calm down is to remind myself that nothing really matters.
And it does bloody hurt the first few weeks like someone's sucking the life-blood out of you! (but once she's latched and drinking, it stops)
and if it seems to be going tits-up take the baby to bed for the day and relax and start all over again.
