Hi JJB (she says wiping baby puke off baby, self and clothes). My ds1 is almost six months now and is exclusively breastfed.
When I was pregnant I was also convinced I would establish a routine from day 1 - HA. Now I realise I was just adding extra pressure and spending too much time wondering what I was doing wrong as my baby wouldnt fit the routines proposed.
I soon gave that up and just followed my baby's lead. Now the only routine we have is bedtime, which has helped to get him sleeping through the night.
He is a very happy, chilled baby and I now have no problem understanding what he needs. Because we dont have a slavish routine, we can take parts in loads of activities locally, and because he is BF, I can go anywhere and feed him at any time.
My best advice to you is to try and find some local mums who will have their babies at the same time as yours - the support and advice and experiences of my new friends has been invaluable. Nothing can beat personal experience - and that is the beauty of MN - someone on here will always be able to answer your questions with reference to personal experience. You can then find out what may work for you. There is no one size fits all solution...
Oh and BF can be really tough to start off with. It didnt come naturally for me, and it took time to establish - about 4 weeks in my case. Take all the help you can get from your MW and HV and join a local breastfeeding support group if you can. I did buy an Avent manual breast pump which is easy to use, but I hardly ever use it cause it is so much easier to just use the real thing! I would suggest that you dont bother buying one until you have established breastfeeding.
