Bahahahaha It's hard to find similarities!!!
Charlie is dark hair, dark eyes and slightly olive skin. He's placid, right handed, loves technology, was an early teether, slow developmentally.
Ollie is blonde and blue with super fair skin. He's firey, a lefty, not so interested in technology - would rather 'do' stuff, late teether, above average developmentally.
And that's just a snap shot haha.
Charlie is full on my side of the family and Ollie is full on DH's side! I've actually had people ask me if they have the same father
But then I've had people ask if they're twins?! WTF?? They're 2yrs 4days apart, but people think they're much closer. There's only a few inches between them, but I don't get the whole 'twins' thing
