if number four does too? I went to the baby clinic to weigh dd (well I didn't go for that reason, I needed a new red book for ds as I lost his and they want to do pre-school jabs) and she's gone from just above the 75th centile to below the 25th in her first 3months. As did dd1, ds1, ds2, they were all born around the 75th, went to the 9th and stayed there forever more, the place where their parents weight is at roughly....
All happy, clever little people (modest me) but skinny and average height. The HV seems to think I'm a bad mum shrugging off the centile drop and kept on at me about bringing her back, really went on and on until I wondered.
2 bottle fed, 2 breast fed, all happy. Am I right to never weigh her again like planned anyway not worry. Never starved a baby, very very content babies, I just have a theory that's how mine grow.
