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.

If you want to get the mum-to-be in your life a really special something for Mother’s Day, or the new mother something that can help her feel feminine and beautiful in the sometimes difficult months post birth, we have a fantastic offer for you.

Boobie Milk is a supplier of maternity and nursing lingerie, and they stock some of the nicest brands of maternity bras and underwear you’ll find. As a mama-to-be with a two week overdue bump myself, I have absolutely loved not only the service I’ve received from Boobie Milk, but also the products, and cannot recommend them highly enough.

So what’s the offer?

Boobie Milk is offering PlayPennies readers 15% off on their range of maternity and nursing wear

Of course this doesn’t just have to be for Mother’s Day, as every mum to be will know pregnancy changes your breasts, in shape and size, and the birth of a child does the same whether you breastfeed or not, so having the option of having an at home fitting if you live in Kent or surrounding areas or an online advice service if you don’t is pretty awesome.

When your body is no longer your own, and your once comfy underwear is cutting into your skin, it’s a real pleasure to be treated to professional and helpful service, and walk away feeling feminine and sensual, bump and all.
