Most new mums have a confidence crisis re their changed body, try not to worry.
On the practical front, why not buy some Spanx or a waist wrap if you’re self/conscious about your tummy? Have you been checked for diastasis? Well fitting trousers and long loose tops could help too.
Skin: try to make time for regular moisturising, toning, masks. Maybe a facial or peel.
Hair: a new cut/colour, lots of deep conditioner, a style that’s easy to blowdry before work. My baby loved watching me use the Babyliss Big Curls for some reason, she’d stand in her travel cot transfixed!
Make up: a good primer, foundation, bronzer or blush, lipstick (a blue tint to the red will make your teeth look whiter).
Teeth: whitening toothpaste paste or ask the dentist for laser whitening. It’s quick and painless.
Make sure you’re taking vitamins and maybe use an anti aging/tightening product on the skin that bothers you? Eye bag cream and concealer.
Boobs: a good push up bra works wonders.
But honestly, I don’t think people at work will care/notice. You’ve just created a new life!
If you still feel self conscious I’d look for a new job where appearance is less important.
I clearly remember my first day back at work after mat leave, I had my dress on back to front and my make up was smudged from the rain. My colleagues (all beautiful attractive women) were so kind.
