That's what the PD said.. "Genetics". However, both me and my hubs are not short. So it really didn't seem to make sense to us then.
I googled about height stunted growth and it pointed to malnutrition, that's what got me worried.
Honestly if he is putting on weight, he can't be malnourished & if he was 5yo & he hadn't grown for a year then yes I'd say you have something to worry about, but at 5mo, I think you might just be worrying a little too much about nothing. I'd have to say if it makes you feel better give him the night feed, but I very much doubt a baby who is gaining weight will be malnourished & have stunted growth, they don't grow in a linear or even fashion (even at 11yo) they have growth spurts where it feels like they grew an inch overnight & then periods where you think "gee you've got chubby, must be getting ready to grow again"
If you are really worried I'd talk to the Dr, but honestly I do think (from experience with my 2) that if they are hungry a pacifier will only tied them over for 20-40mins, if it is 3-4 hours then they really are coping with the amount of food they are getting in 24hours.
OK I just went & looked at both my boys "health books" DS2 was more consistent but this is DS1 (weight was always up at 90%) These are rounded to the closest line
Birth 97% for height
3mo 75% for height
5mo 60% for height (not yet rolling)
9mo 75% for height
10mo 50% for height (not yet crawling)
11mo 75% for height
14mo 50% for height (not yet walking)
18mo 75% for height
2.5yo 75% for height
5yo 90% for height
8yo 90% for height
10yo 97% for height
11yo 97%for height.
So basically it took DS1 until 10yo to be back at the same spot on the chart as he was born at & almost before every movement milestone he got "chubby" & short by comparison to his average.
Even DS2 who is tall dipped between off the chart (he was born at 58.5cm/23inches) at birth down to 90% here & there.
