Heat oil, in a large saucepan, over a medium high /heat. Add onions, reduce the heat and saute until softened (around five mins)
Add the garlic and stir for a further minute.
Peel and dice the potatoes, add them to the pot and cook for around 2 minutes.
Add the stock, bring to a boil, cover and simmer for 12-15 mins.
Add the peas and continue to cook for a further 3 mins.
Add the lemon juice and then blend the soup (I used a hand blender) until smooth. Add the mint and blend again.
Taste and season, adding more mint if desired.
Notes
If cooking for a baby use homemade stock or baby stock cubes.
If the soup is too thick you can add some more stock to thin it.
If you do not have a stick blender, allow to cool slightly before adding to a blender or food processor to blend.
You can add all the mint before blending but mint can be quite a strong flavour for kids. Start with a little mint, let them taste it and add more if desired.
