Mamas & Papas Pushchair Sunshade £6.99 (was £17.99) @ Argos
Argos have these Mamas & Papas Sunshades hugely reduced at the moment, down in price from £17.99 to just £6.99 and they are selling very fast.
There's two patterns, a pink and a blue, and they are designed to protect your little one from the sunshine and provide a shady and cool spot to sleep.
These sunshades have UV50 sun protection, and have mesh sides for ventilation as well as a 'window' so that you can check on your little one.
They are supposed to fit most pushchairs, not just Mamas and Papas ones, though they cannot guarantee a perfect fit on every pushchair, but a quick read through the reviews suggests that parents have used them on many brands.
When not in use the sunshade can be folded up compactly into it's own carry pouch, so this is ideal for keeping in your baby changing bag for sunny days, daytime naps or on holidays.
You can reserve and collect for free from Argos stores, or home delivery costs £3.95. As this is a Clearance item stocks are a little hit and miss in some areas, though there do seem to be high stock levels in most places.
