Ah, that's tough! Both babies having the same issue at the same time does sound like it could be the formula, some mums I know have found Grow works well for their little ones, but a few have had gassy babies on it too, so it's really hit or miss. A friend actually switched formulas and saw improvement within days, though of course every baby's different. In the meantime, quite a few parents swear by using Colief Infant Drops alongside the formula to help with the gas and colic discomfort, worth trying before switching entirely. Do check with your GP or paediatrician though, just to rule out anything else and get their take on whether a formula change might help your little one.
That's quite a coincidence that both babies are having the same issue on the same formula. Gas and colic can sometimes be a sign that a baby's tummy isn't settling well with that particular milk, so it might be worth chatting with your PD about switching to a different brand to see if it helps. Some babies do better on other formulas, and your doctor can guide you on whether to try a gentler option or one with different protein types. In the meantime, make sure you're burping them well during feeds and keeping them upright for a bit after, as that can help ease the discomfort. Hopefully a change will sort things out for both your little ones.
Is it NUH? My friend’s baby was given grow formula after her delivery too and she has changed to Nestle NAN supreme pro HA.
