12 week old weight

[mill1969]

Has anyone had a baby that dropped a centile ?
My formula fed baby was on the 50th centile and when I had him weighed yesterday I was told he has dropped down to 25th centlie. Is this normal and can he go back to the 50th or will he stay on 25 now?

Hello - my baby dropped a centile but visually looked fine, so no one was v worried. The midwife said it was quite normal. If they were concerned they would have spoken to you about his diet and how regularly he was having milk. I wouldn't worry about it, not every baby 'obeys' the charts:) My baby only went back up to her previous centile at 11 months.

For a baby who is well and developing normally, a drop (or rise) of up to and including two centiles is perfectly normal. So 50th to 25th is well within normal. Hope they told you this at the clinic. Not good practice to weigh babies too often - once a month under six months is sufficient, and once every 2 mths aged 6mths to a year.

He might go back to the 50th but it doesn't matter if he doesn't :)

They didn't tell me it was normal at the clinic , just said that I would have to get him weighed every month from now on. I was also worried that his predicted growth as an adult is going to be much smaller now he's dropped down. My partner is the tallest in his family at 5'7' and the rest of them are under 5' and I would like him to be a bit taller really!

Every month weighing is fine. They surely didn't suggest the 50th to 25th was not normal, though, did they?

I can promise you that your baby's weight at age 12 weeks predicts nothing/zilch/zero/nada about his adult height.

If he is going to be smaller than average, then genetics will play a far, far stronger role than his weight age 12 weeks.

They didn't say it wasn't normal but they did start talking about maybe having to take him to the docs for a check up if he goes down again next month. According to the red book you can calculate a baby's height by the centile he is on.

mill, sorry you have been made worried by the clinic - does your red book say you can predict adult height at 12 weeks when weight is still quite volatile? That's odd.

The information on the chart I have about predicting adult height says this: 'The child's most recent height centile (aged 2-4 years) gives a good idea [of adult height] for healthy children' and it tells you to plot this height centile on the predictor tool. In my copy of the red book there are a couple of paragraphs on length and height and it repeats the stuff about predicting using the 2-4 years height chart.

Maybe you could ask the clinic for clarification on this?

I have the same info as Tiktok in my red book, and the height predictor tool seems quite accurate (we did it yesterday and apparently DS should be aiming for 6'3 - 6'7. Argh).

But I don't think you can acurately predict adult height using an infant's weight. Otherwise there would be no tall, skinny people. And at 12 weeks, he'll be changing all the time.
