DS3 been very windy and constipated on SMA so (after getting recommendations here on MN) decided to try Aptimil - he's been having it since yesterday evening and has been even worse, hardly settling as he's waking up windy (bottom end) and generally a very grumpy baby, screaming, straining, farting, and quite miserable........I'm now about to chuck out the bottles I have made up (yes I know the "recommendation" is to make up when you need them but we don't - ) and go back to the SMA.
