Baby's first words are such a huge milestone. Not everyone remembers their first word, but it's such an important moment. Albert Einstein was rumoured to not have said a word until age 4 (although the standard is around 12 months). 

Aside from words for "mummy" and "daddy", the most popular first words according to The National Literary Trust Fund, are: 

1. Dog
2. Cat
3. More
4. Baby
5. Ball
6. Duck
7. Teddy
8. Milk
9. Gran
10. Again
