Kinda want to cut back

EmpireMomof3

DD is just about 17months now and still nurses on demand. That equals wake up / breakfast, lunch, before & after nap, dinner, evening, bedtime and 1-3x during the night. She is offered food all the time but chooses to nurse. She's very picky on what she will eat. She hates WCM or juice and will drink water from a sippy all the time. 

I nursed our older boys until they were 2ish, but being she's our last child I don't really want to fully wean her... just cut back a bit.   Maybe the night feedings or during the days so when we are out and about. Those tantrums can be brutal when I try to deny her during outings. 

So, got any ideas? Suggestions? Links? Thanks.
