Hi!
The DF isn't for all babies......
We didn't start it to quite late GOKW? I was having a convo with a friend one day and thought it would be a great idea
...turned out to be the biggest 'tie' I could imagine!!!! and it was bugger to wean, so if your bub can manage without and sleep thru, (obviously you are yet to test this theory!), then I would go without. Our bub slept thru without it , it wasn't till I introduced it that she would start to wake!!! Go figure.....
HTH
ps I'd be wondering if 2oz was worth it too, what time is the last feed before that I think ours was 9pm and then about 5am at that stage
