My son is still in newborn but he is quickly growing out of them

My little one was weighing 7 at about a month lol she was born 5 pounds 2 ounces 18 inches long lol it's been probably 3 days now that she stopped using her newborn clothes and started using her 0-3 month clothes

Lol he was born 6lbs 14oz 20 inches long @pikapal

My baby girl is barely 2 months and she's barely weighing 9 pounds 😭 lol
