I'm a complete novice when it comes to making for boys, so I'll also be watching with interest. Theo is only just 11 months, but he had a very long body, and a prominent baby tum.
The rompers fit far better than the shorts I made yesterday! Having said that, the shorts were an Ottobre pattern, very easy, they have front and back pockets, faux fly, and back waist elastic. I'll be making a few.....
