I bought these for my 4 month and 3 week old baby to wear for easter- they are adorable! As many reviews said, rosie pope shoes do run large so i purchased the 0-3 size for her. Theres a bit of room in the shoe, but these won't be worn for more than maybe 2 months. No worries, adorable for the time being! Rosie Pope is by far my favorite children's brand thus far- check out her pjs!!!
