Tiny newborn in a Diono R120?


New member
My friend 3 Diono R120s in her Honda Accord for her 3 kiddos. 2 are FFing, and the baby born today is RFing (obviously). Baby was born today weighing 5lbs 13oz and is 19" long. Is he going to FIT in the Diono R120? Does it work that well with tiny infants with the insert in place?

He'll grow quickly. Mama has a uterine septum which makes her grow small babies, but by a month they're usually in the normal range for weight/height. I just worry about right now. They will be out and about quite often once they're home from the hospital, and I won't be able to get a good look at his fit in it until next week.

It is unlikely that a baby that small will fit right away. :( My 7lb kiddo (who was quite tiny) didn't fit until she was 1-2 months old.

Thanks for your response! I was wondering if that would be the case. :( She has a Graco Snugride 32 but it's too wide to fit with the Radians. I don't think they have the resources for a new seat right now, either. And all I have are Radians or I'd lend one to her...

I am going to visit them on Tuesday and will take a closer look. I had a feeling the seat would swallow him.
