It's widely known that pregnancy can make a woman grumpy. That’s definitely true in my case - at 18 weeks pregnant with my third child I am prone to the occasional hormonal flip out, and have begun to contemplate wearing a t-shirt emblazoned with the warning: Angry Pregnant Woman: KEEP CLEAR.

But if there’s one thing guaranteed to keep me calm and get the happy hormones flowing at this stage, it’s hitting the treadmill for half an hour or going for a (very graceless) run along the beach.

Which is why it surprises me that it’s so difficult to find decent maternity sportswear. I have Googled endlessly for running togs that work with a bump but so far my quest to feel comfortable whilst working out with a baby on board has yielded nothing.

Until last week when, on the brink of giving up trying to wriggle into my normal running gear, I stumbled across www.boobiemilk.co.uk and the wonder that is the SportJock Action front-fastening sports bra. I honestly almost wept with joy.

At £25.99 and with a zip-fastening front it’s a joy to put on - pregnancy can be undignified enough with having to suffer the humiliation of trying to squeeze your melons into a pull-on sports bra. And with no wires, it’s ideal to wear both as a standard maternity and / or nursing bra, or when you need some extra support whilst exercising during pregnancy (or in my case, attempting to).

Mine’s grey and the sizing is super-easy to figure out: small, medium or large. The CoolMax and Supplex fabric really does keep you cool once you work up a sweat, but unlike so much maternity wear, the SportJock Action bra looks pretty cool too.

Which in my view makes it priceless.

Mammae Bras are a new maternity bra with a patent pending and a registered trademark due to their new way of providing discreet, comfortable and simple breastfeeding.

Mammae have front opening clips, rather than the standard shoulder clips, which open up to the side to reveal a split front shape hugging stretchy lacy bit for your nipple to protrude through. You can also buy breast pads that match your bra and add to the very pretty and luxurious feel of these items.

These are underwire nursing bras, and apart from the actual breastfeeding, it’s almost easy to forget that you aren’t wearing a pre-baby brasier.

I was sent the Mammae Plus Taupe Treasure to review, and it is a beautiful nursing bra. It is, obviously, taupe and black in colour, with a lovely lace detail and a ribbon above the clips. While they say it’s a one hand opening clip, it does need a bit of wear before you can actually do it with one hand – I struggled to do it one handed for the first while.

BoobieMilk currently has 15% off any lingerie from the gorgeous HotMilk range with the voucher code below.

The HotMilk range is gorgeous, and provides fantastic support – especially for the larger breasted woman – while still leaving you feeling sensual in your undies. No granny pants here.

The fab thing about the code is that it also works on the items already on sale, so for items under £20, the discount code basically negates the £3 postage fee, but if you spend more than that you save more.

For example, the Radiance Nursing Bra is £33, discounted to £14 and then 15% comes off that, add £3 for postage and your total is £14.90 – an £18.10 saving. Enough to buy another one!

If you spend £60, you’ll save £9 and have your, spending a total of £51 and free postage and at least two to four new sets.

When I was pregnant with my daughter I went to a well known baby shop and bought a few nursing bras. I didn’t really see the point of ‘special’ bras for breastfeeding, so wasn’t interested in spending much money on them.

This time round I was given a couple of Bravado nursing bras and I am seriously surprised by the difference in quality and feel.

I’ve been wearing the bliss and seamless bras for a few months now, and have to say that I am in love with these bras, even if I wasn’t pregnant and breastfeeding. As a fairly, erm… endowed, woman, I often find that bras simply don’t offer support and even with underwire I can end up with my cleavage looking quite droopy unless the straps are quite tight, which sometimes means they cut into my shoulders.

With the Bravado bras I’ve not had that problem. They have something called Flexi-Fit which is a substitute for underwire and the support is amazing. They also have a foam pad layer which gives your breast a lovely shape. And if you’re wearing a nursing pad to stop milk leakages, you can’t see it through your clothes as the foam layer provides a false second skin.

The Bliss Nursing Bra has beautiful detailing and a touch of lace, as well as a plunging neckline and silky finish, so even though you’re wearing a nursing bra, you can feel feminine and sensual in your underwear, rather than just functional and motherly.

It also comes with an additional clip to give you extra cup size as your breasts expand, and an additional back clasp to give you about five centimetres of growing room, which I thought was a really nice touch.

The  Body Silk Seamless Nursing Bra is completely seamless so if you’re wearing anything skin hugging, there are no unsightly lines.

As someone who spent the first two years of motherhood not understanding why people would spend money on nursing bras when you can get away with using your normal bra throughout, Bravado have converted me, and I can imagine wearing these long after I’ve stopped having and nursing my babies.

Bravado don’t have a UK shop, but there’s a list of retailers here that sell their products.
