After breast feeding dd3 for 10 weeks and realising that the back ache was because my daughter was getting too heavy for me to hold in position without slouching I bought the My Brest Friend feeding support, its expensive but as I justified it to my husband (who nearly had a heartattack at me spending £45 on it), if it helped me to carry on bf for another 6wks it only cost the same as buying formula. 14 weeks on I still use it and wish I had bought it when my eldest was tiny! I had a stack of cushions for her because she was a tiny premature baby and used to feel like I was losing her in them sometimes. I've recommended it to everyone I know who is planning to bf and will carry on using it as long as I can!
I also love the feeding tops from JoJoMamanBebe and the NCT shop, no-one has ever realised I've been feeding while wearing them and I find the aprons a hassle with 2 young toddlers to deal with as well, does require a bit of practice at home wearing them first as every top is slightly different!
I also admit to having a bit of a thing for pretty nursing bras and making sure I have the matching sets where possible (not easy when trying to get 30F!). I always feel better in nice underwear and don't see why that should change because its a nursing bra!
I think all the above helped me exclusivly bf dd2 for 8 mths before she finally accepted food was for eating not throwing at the dog and I'm aiming to try and do the same with dd3.
