Hi,

Was the nurse worried about the crossover in percentiles? What did they suggest?
It is generally pretty normal for babies to cross percentiles. I am guessing he hasn't actually lost weight, just gained weight more slowly. What percentile was he on? And how many feeds would he have in 24hours?
The percentile your baby is born on has more to do with conditions in utero - if your placenta worked really well, and your nutrition was good your baby might be born relatively bigger than he was genetically meant to be. At some point he will need to "grow" to his genetic potential. Thus the cross over in percentiles.
