Boys name dilemma

I really like your shortlist! My order would be

1. Dylan - cool and simple, not too trendy or overused / dated. Love it.
2. Alexander - timeless classic, safe choice
3. Jonah - nice traditional name, but with a modern sound (lots of names like Noah etc popular with similar vibes - Jonah is less overused)
4. Caleb - good solid choice too, not overly commonly used.

Alexander - this will undoubtedly be shortened to Alex!
Jonah - I actually like this
Caleb - not a fan!
Dylan - really like this

I agree with the above poster that you should narrow it down to 2. I don't think babies "look like" a certain name when they are born but narrowing it down to 2 might help you choose! Names are personal preference though, you are going to get posters who hate all your choices, who love all your choices and everything in between. Once you and your other half love it, that's all that matters. You are the ones going to be saying it for the rest of your lives. Congrats and good luck

I don't think you need to know before you've met him. I would just focus on halving the list and that takes the pressure off
Before having ds we had 3 boys names for months. Narrowed it down to two very close to the due date and as soon as he arrived me and DP looked at each other and just knew which one was right for him

Congratulations! Xx
