How much does your 4 week old weigh?

He is 8.11 at 4 weeks, which is the 24th percentile, he was born at 7.6 and my pediatrician said by one month they want them to have gained a pound and a half to two pounds. He was on the low end of that.

  • What did your Pedi suggest? Did he say anything you should be doing or is he worried?

     

  • I have never heard the 1.5-2lb by one month.
    #1 went from 7.8 to 8.5
    #2 went from 7.13 to 8.8
    #3 went from 7.13 to 10.3
    Pedi was fine each each baby's rate of weight gain

    If he's in the spectrum that your pedi suggested then I wouldn't worry. Personally, I haven't heard of 1.5-2 lbs by 4 weeks but I'm not a pediatrician.

    My LO was born at 8lb, 6oz and at 4.5 weeks was at 9lb even. We tried to breastfeed but I had supply issues, he was very dehydrated early on as a result. He's now 7 months and is perfectly healthy.

    I wouldn't be concerned.
  • My pediatrician told me that they like to see a 1.5-2lb weight gain within the first month. My son gained that but she was still a little concerned as he is on the small side. 6lbs when we brought him home and 7.8 at 4 wk check-up. Dr was happy happy overall with weight gain just concerned bc he is in small.
  • Pediatrician said as long as he has wet and poop diapers frequently then he is getting enough milk.
