お母さんに目と鼻の感じが似てるって英語でなんて言うの？

A) Wow, he/ she is a carbon copy of you.
Carbon copy -a person or thing identical or very similar to another.
Example-"the children were carbon copies of their father"

B) She defiantly has your eyes and nose.
*Defiantly - certainly / for sure/ without a doubt

I Hope this helps :-)

The baby's eyes and nose are a copy of yours(referring to the mother)
copy of yours = identical;look exactly like yours

1. The exact likeness. "She's the spitting image of her mum."
2. Alike = two or more people or things which are similar to each other
3. To look very much like someone else. He's the dead spit of this bloke. This is Australian slang.
   "That boy's a dead spit of his brother."

When you want to tell someone that a newborn baby has a similar appearance of their mother, you could say "She's got her mother's eyes and nose."

"It has its mothers eyes and nose"
"He has similar features as his mom, like the eyes and nose."

Both of these expressions are a proper way of saying this. The first expression is informal, used more often between people that know each other such as friends and family. The other expression is used often by people who do not know the person or maybe are describing a person they saw.

When describing a newborn oftentimes, persons describe this as having a splitting image of their parent. This basically means that they look just like them. You can be more specific and say that the baby has the parents eyes or nose or mouth but those are typically the main features on a baby.
