Hi. I breastfed till 6 months and didn't wean till then either. I found it quite hard-going and also that expressing milk took ages. I wanted to carry on as long as I could, as I enjoyed the bonding between me and dd and also because of the health benefits, but I found it quite restricting as I was never comfortable about feeding in public.
When dd started eating solids, the number of milk feeds went down but I decided to give her the odd bottle of formula when it was inconvenient to breastfeed her. After a while, I realised I was only bfing first thing in the morning, last thing at night or to comfort her when she was upset. This then dropped to only the last feed of the day and then finally, when she was 17 months, we stopped altogether.
I wish I could have breastfed exclusively until she was three or whatever, there are health benefits, but I felt the above was an acceptable compromise for me and dd. You don't have to completely give up unless you want to.
If you are going back to work at 10 months, it would be wise to get your baby used to drinking from either a bottle or a cup with a spout in advance. My cousin had problems with her dd refusing to drink anything unless she was bf. This went on for about a week with her dd at nursery starving herself during the day, and dehydrated, and then wanting to bf all night, exhausting, before she would take a bottle.
I agree that, if you do decide to stop bf, or stop bf exclusively, it might be possible to miss out the bottle stage altogether and go straight to a cup. I didn't do this and my dd is now 2.4 and still has a bottle at night. I will have to wean her off this one of these days but she seems to find it comforting so I haven't the heart yet.
