“She’d be like ‘Cosmo, now is it final? Like did you submit the birth certificate, she’s like ‘Oh, OK. Interesting. ‘Cause I was reading there’s also a name Cosimo, with an ‘i’. So that could also be an option.’ ” he added

“She lives in Staten Island, eventually she started meeting various members of the Italian community who have a lot of Cosmo relatives. So then she would call and she would say ‘I met someone they said their uncle’s name is Cosmo. So, it is OK,’ ” he concluded.

I was just like, ‘Oh my God,’ It’s crazy. It was just so intense. No reasoning, like very intense emotional swings and so bossy and adamant … these huge mood swings, constant mood swings, which I was like, those poor little guys, I feel bad for them. It must be a lot. You’re like up and down constantly.” Johansson continued.

“You get a lot of grief from toddlers, like everything you do is not right, which is hard,” she said.

“I’m very fortunate I’ve had time to enjoy my early motherhood and not be working tirelessly. When I had my daughter, I think at this point I was shooting ‘Captain America 3,’ it was a lot to jump into. I was very thankful to be working at that time, and now I’m very thankful to not be.” she added about her experience of motherhood with her daughter.
