https://vm.tiktok.com/ZGdYbLeGQ/ this account has really good guides and advice. Also go based of your baby, my LO has always ran warm so doesn’t always need the same layers that another baby would need as he overheats easily
There's a really good app called babywear that gives recommendations based on the weather info for your area
My little one wears a vest, a onesie indoors. I put a cardigan on her when in car seat then a blanket tucked over her when in car. I did do two blankets until car has heated up and remove one. In the pram she will be in a pram suit and I unzip when in shops x
