What size diapers and clothes are your babies in?

My daughter was born at 37 weeks, 5lb 14oz and 19 inches. She turns 4 months old on June 21st and still wears size 1 diapers. The flaps touch each-other in the middle because her waist is so tiny. Is that normal? She’s also in 3 month clothes but some newborn can fit her.
