Interested Leo

This is my best friends son saying goodbye to Lola as we were about to leave. He's around two and a half months older than Lola and we were saying today they seem to move on stages at around the same time but onto the next thing, Lola started to roll as Leo started to sit up and now Lola's sitting up as Leo crawls and he's about to walk as Lola is about to start crawling, cute.
