How to choose a middle name for Theo

Now that you have lots of ideas for a middle name how do you actually make a final decision?

Here are a few tips to help you along the way in picking a middle name:

Sound it out. Think about how the first and middle name sound with your surname. Does it work together?

Write them down. Seeing your favourite names written down can really help you to decide whether you both actually like them or not.

Each choose your 5 top options. If you are struggling to agree on a name with your partner then each write down your favourite baby names. Stick your lists on the fridge and take a week to think about it. This way you can both take time to look at the name options and see if your opinion changes or strengthens over time.

Take note of the initials. You may miss the initials at first glance but if they spell something unfortunate then you may regret picking the name! So always write out the initials of the first, middle and last name and decide if you’re OK with what that spells out.
