Madeline was 17lb 1oz at 24 weeks. Her weight gain did slow right down, but she has gone up to the 75th centile after following the 50th line from about 8 weeks (she was on the 25 line before that). She is on solids and not yet moving anywhere, so kind of expected this. Our LOs are not too far apart in weight though - and being on the 50th line is perfect.
