Pregnancy clothes with second babe

Hey everyone!

I am due March 5🥳 this will be our second babe. My first babe I was pregnant during the summer so I don't have much winter clothes.

For those that are pregnant with a second or have had a second babe. How did you decide what size maternity clothes to buy? Did you just wait and try them on or guess and they fit? I am normally a 12-14. I feel like I am going to be bigger with this babe so I don't know if I should buy my size or size up.

Thanks for your help💕
