EBF weight gain at 1 month

My EBF twins just had their 1 month appt yesterday and I'm so happy at how much they've grown! I just wanted to share my excitement with someone lol. They were 5#12 & 6#1 at birth and 4 weeks later 8#12 & 8#13!!!! I feel like I'm feeding them literally all the time and the most either of them has gone in between feeding is 2.5 hours tops so I'm super excited all my hard work and sleepless days/nights have actually made a difference. 👶🏻💕👶🏻
