I'm no expert but 5 feeds seems plenty for a 14 month old. At this stage it's very normal for them to be interested in doing other things rather than stop and drink. Many other kids this age make do with just 1 or 2 feeds a day and your body should adapt to make just the right amount of milk she needs.

I had a lot of trouble when my DD was born as I was given some very bad advice saying I had a low supply. Even after I saw a IBCLC who confirmed there was nothing wrong with my supply I still took a long time to stop worrying about it. When DD weaned herself at 24 mnths and 2 weeks she was only down to 2 feeds a day and I had no trouble making just that amount of milk. I think the only reason my milk dried up fairly quickly afterwards was because I am pregnant. I only lasted a couple of months though, I have colostrum already and have that beautiful full boob look back . (Sorry, couldn't help myself as I've always had v small breasts)

Anyway what I was trying to say before I got sidetracked is that as long as you take it slow your supply should drop only enough so that you are still making all the milk she needs but you won't still have that overfull feeling or be spouting milk everywhere. Oh yeah, since we cut out all the night feeds for DD my boobies were flat and really empty feeling and yet I was still making all the milk she needed (about 4 or 5 feeds a day at that stage) so don't get fooled by what it all looks or feels like.

Good luck and don't worry too much.
