Jessika • ❤️ 25 year old mommy to a six year old little man9/9/12 • lost my sweet 2nd son 9/5/17 31 weeks 6 days • rainbow baby girl born 11/12/18
I have a son who is 4, he has a double first name which I picked and I love! 
I have a double name for if this little one is a girl but I need boy ideas! 
I really am set on keeping all my Little's with double names! 
Any ideas? (: 
Thank you ! 
P.s. Son is DavidRyan if that helps!
