i would really recommend The Master Cleanser fast for 10 days, especially since you have a baby!
on a Water Fast you are getting no nutrients so you might start to lose energy, but on The Master Cleanser fast you have a lot of energy (i'm on day 7 and feel pretty good). i would explain it some more, but i've responsed to a lot of these posts already and don't want to keep repeating myself. but there are lots of resources on the net about the MC. i would check it out if i were you.
