Tiny baby consumed by gas (7)

I believe the answer is:

neonate

I'm a little stuck... Click here to teach me more about this clue!

'tiny baby' is the definition.
'neonate' can be an answer for 'baby' (medical term for a newborn child). I'm not certain of the 'tiny' bit.

'consumed by gas' is the wordplay.
'consumed' becomes 'ate' (to eat is to consume food).
'by' means one lot of letters go next to another.
'gas' becomes 'neon' (neon is a gas).
'ate' after 'neon' is 'NEONATE'.

Can you help me to learn more?

(Other definitions for neonate that I've seen before include "Young baby" , "Young infant" , "produced baby" , "very young child" , "recently delivered" .)

I've seen this clue in The Telegraph.
