Girls, hello everyone. Such a question, who gives birth in summer, what will you take the baby out of the maternity ward? And still, what size should I take things for, if the baby is big, just my three were all 4 kg, and I remember some sliders they gave us right away they were babies. Just my youngest daughter is already 9 years old, I don't remember what size clothes she took. I want to order online, so I'm afraid I'll make a mistake with the sizes.
