Name help. Double "EE" or no "EE"

So long story short (kinda) ☺

My name is Mckinzee

My sister is Destinee

I always loved that we had that in common because we were not close in age ,5 year age gap.

Well I had my first 2 daughter's 5 years apart too....

So my 16 year old is

Chloee Lynn

My 11 year old is

Kallee Marie

Pronouced like KAL-lee

So what do I do now? I'm almost 5 months pregnant and

Its ANOTHER GIRL!

I am feeling so confused on if I continue the "ee" or say no more. My youngest says yes yes!

my oldest says no no!

Please give advice and/or suggestions.

Thank you
