They've seen you through the tough times, they've seen you at your best and your worst, and they know every single thing about you (even if you don't want them to!). Just where would you be without your gaggle of friends?
From the one who tells you like it is to the one you trust your kids with, here are 9 BFFs every mum should have...
1. The 'says it like it is' friend
She will tell you like it is even in the toughest of times. If you want a straight answer, it's round to hers for a cuppa, catch up and she'll tell you the hard honest truth - even if you don't want to hear it! Well, what are friends for?
2. The friend who's more like sister
You've known each other for as long as you can remember. You just have to look at each other and you'll know exactly what the other is thinking - you're more like sisters than friends and you're convinced you were separated at birth.
3. The 'treat yourself' friend
You love shopping trips with her because she always makes you feel good about yourself, even when you're fed up of wearing the same old clothes or yet again you're counting the pennies. Her favourite sentence is 'Oh go on, treat yourself. You deserve it!'
4. The feeder
She smells like freshly baked cakes on a regular basis and you're sure she lives above a bakery! She always invites you over for a cuppa but it's never just a cuppa - it's a tray of flapjacks or a stack of biscuits too. If you're meeting up for lunch, she decides where and you let her. It's the perfect relationship!
5. The friend who knows you better than you know yourself
She knows just about everything to do with your family - from your husband's annoying eating habits to how the kids are addicted to Peppa Pig. You're not even sure how she knows this, but she does!
6. The friend who loves a laugh
Something always triggers her off and then once she's gone, you're gone too. You stand outside the school gates rocking backwards and forwards laughing until your sides split. Sometimes you don't even remember what you were laughing about in the first place!
7. The child-minder
Whether you're stuck in traffic, late leaving work or there's been a household drama, she's always there to lend a helping hand when it comes to sorting out the kids. You owe her - big time.
8. The hyperactive competitive
She's always up for a night out with the girls, as long as there's a pub quiz she can get her hands on. You've baked an amazing birthday cake for your daughter, well; she's baked an even bigger one for hers! It's a competitive friendship that you see the funny side of (luckily!)
9. The queen of gossip
She spills the gossip, she gets the gossip, she is the gossip! She's bursting with rumours and is always the one to fill you in on who said what and who did what to whom. Her life is like a soap drama, you just can't keep up with it!
