Help with choosing the best front pack/ carrier

Hi everyone , I’m looking for help with choosing a baby carrier. I have a 4 year old son and expecting my princess March 22. I never used a carrier with my 1st so I’m not sure what’s the best one to get . I will need it for everyday use. I have a bad back so I’m looking for one that has back support and for one that allows the baby to face forward and backward. It going on my back would be a bonus. Also don’t want one to bulky. If any of you moms have a carrier you prefer and love please send a link if possible in the comments or even just a picture and name of which. Thank you so much 😊
