It does depend because some girls change heaps and others don't. There are many people who say it's a good idea not to wear wire and I would agree with that. I got a couple of maternity bras - one fitted at Myer that was about $40 (Loveable brand) and then a couple of cheapies from Kmart. All were good and comfy. I wore them for most of my pregnancy.

Since I've had Mackenzie I have barely worn them because I am totally in love with the breastfeeding tank tops! You can get them from ABA shop or MYer (prob other places too). They are like a maternity bra but with tank top so it means when you lift your top to feed, you can't see tummy - VERY important to me cause I didn't want to show of stretch-mark, squishy belly!!! I also didn't want to buy heaps of tops that could be pulled open from top.

The tops are about $60 for Glamour Mum brand but I wear them all the time - so comfy and easy and go under most tops. I have a couple of cheaper ones too that are good for night time - not quite as supportive but still really comfy. they are Loveable brand. I would def recommend those but up to you! You can buy them for pregnant belly's or after belly too.

Good luck!
