Mom and baby freebies 🤔

So every since changing glow over from fertility tracker to pregnancy my Facebook and Instagram have been throwing ads at me for free baby and mom clubs and kits . I’m really interested and getting a bunch of stuff to try out as this is my first pregnancy and baby so I don’t know what products will work for me best . Does anyone know what freebie ads actually work and worth it or are they usually all scams 🤷🏻‍♀️
