baby name change help! long sorry!

I am having the hardest time with a baby name change! We have had the name Noah picked out since we found out he is a boy. I'm now 29 weeks. I really like the name Noah but I haven't been 100% in love with it. The reason we picked it is bc it was the name I liked the most and it sounds great with our older sons name (Knox). About 4 days ago I read the name Hank and I got all the feels lol! I felt the way I felt when we found Knoxs name! Super happy and excited and really in love with the name Hank! I have spoken to my  sweet husband and he says he loves both and I have the ultimate decision so he supports me either way! I just feel so guilty!! My son is almost 3 so it's hard for him to understand the name change and keeps calling him Noah. It's only been 2 days though since we started calling him Hank. My family is not supportive and keeps saying they like Noah better and making it so much worse. I wish I would have kept his name a secret from the beginning or waited longer to decide :( I'm so stressed over this, it's all I can think about! I still have not totally decided on changing his name bc of all the stress. I am writing bc I feel like I can be honest on here. I don't want opinions of the names just maybe some support or a success story of a name change! Thank you for reading! :)
