1st time parents. Would like opinions as to what makes a good/useful changing bag. Got the free boots one but it seems tiny/narrow opening at the zip. Think id like a wider opening neck if that makes sense. Have seen the dotty one online from next www.next.co.uk/x534332s1#881547x53 altho it may be pants in real life, it looks good in the book though. Like the shape of the yummy mummy ones but can't justify the cost & secondhand ones on ebay seem to have taken a battering. Ideally dont want to spend any more than £40. Any suggestions would be greatly appreciated. Thanks
