Baby Boy Nicknames Starting with L!!!

Ashley
So, I'm expecting my third baby in October and I don't know the sex yet. My kids names are Olivia (Livi) and Lucas (Luke) and I think we want to stick with L names or nicknames. I like Leyna for a girl, but I'm stuck on boys names that I like and will fit with my other kids. The actual boy name doesn't have to start with L, but I'd like the nickname to!!! Help me please, ladies--please and thank you!!!!
