I felt this post in my bones! Currently 10 months postpartum with baby #2, and 2 stone down, 1 left to go.
Have you had your bloods done? Hypothyroidism is very common postpartum, and not commonly talked about. And is your cycle regular yet? TMI Q but usually women feel so much better when it is and when there is regular ovulation. This can take up to a year postpartum, longer if you're breastfeeding.
The biggest change for me looks wise has been upping my protein to 100-130g a day. I'm still EBF so I used an online calculator to work out my calories for weightloss while maintaining milk supply, and use MFP to track everything. I drink 3 litres of water, and get 10-12k of steps a day. I throw the rain cover on the buggy and one of my kids naps is a walk for me. Huge changes to weight, mood, and skin since I did that!.
I also stopped eating every time my children do. I don't need to snack between meals, or finish their snacks any time there's food left on the plate. I keep coke zero and chopped low calorie fruit in the fridge for if a sugar craving hits me (watermelon & mango are the nicest!)
For glowing up, I put a picture of myself in ChatGPT and asked for a colour consult. Found out what shades suited me, and asked for advise on hair colour & make up tones.
I don't have time (or funds) at the moment for expensive beauty treatments, so I dye and wax my eyebrows twice a month at home. I do an everything shower twice a week, and chuck lavender oil in the shower drain so it smells nice. I don't have time for an extensive skin care routine but I wash and moisturise twice a day. I put brow & lash mascara on while my kids eat breakfast. I file my nails and push my cuticles twice a week, and moisturise my hands at least twice a day if I can.
