Neil Patrick Harris and David Burtka recently added the role of parents to twins to their list and the How I Met Your Mother star couldn’t help but share on of their first milestones on Twitter this weekend.
“The tots both started laughing. On the same day,” Neil tweeted about his in sync twins, Gideon and Harper, on Friday.
The funny man says that hearing his babies laugh makes him happier than ever.
“I’m now obsessed with getting them to do it. Babies laughing is like opium,” he gushed.
David and Neil welcomed Gideon and baby girl Harper via a surrogate mother in October of last year.
