mammaemma, you shouldn't feel bad or guilty about this as long as you feel you have made an informed decision and it's definitely what you want to do.
it's not a very easy thing to undo if you decide afterwards that you've made the wrong choice, so i wo9uld say perhaps stick with it a bit longer to make sure you're certain,.
i say this from the POV of someone who gave up bf at around 4;5 months with my firzt child. i was gutted and it took me a very, very long time to come to terms with it, i felt awful.
i've since successfully breastfed 2 other babies.
it IS hard work in the early days, there is no denying that, but i can honestly say that it does get easier, and having done both it really, really is much easier andless time consuming than bottle feeding in the long run.
i wonder if you have a local breastfeeding cafe or something? sometimes it can help to talk to other mums who are experiencing the same thing as you (ie, difficulties feeding out and about) and you cqan usually get some good tips from the more experienced bf'ers about how to get round it.
anyway, like i say, if you're sure you're making the right decision then there really is no need to feel bad about it. you have to do what is best for you and your family
