Thanks for the advice guys! He had his appointment and his dorctor recommended giving him a half ounce of pear juice once a day and it has worked wonders to help soften his stool!
Have you tried laying him on his back, holding his feet and pushing his knees up towards his chest? That's supposed to help when baby is trying to go but can't.
I'm in Australia and have seen Coloxyl for babies at the chemist - not sure where you are or what age you can use it from.
I also have a friend whose baby son had the same problem and the Dr told her to put some prunes in boiling water and leave to soak overnight, then let him drink some of the 'juice'. Prunes are great for helping adults with constipation but obviously can't be fed to babies which is why she told her to give him the juice. I would probably check with the Dr before doing this though, just in case. Good luck, hope you're able to ease his discomfort :)
maybe add a tad extra water to his formula. I have heard of this for constipation. As far as gas goes my best advice is to make sure you burp him very well after each feeding
Glad it's all sorted. I wouldn't add extra water to formula as it's all done precisely so that it gives the correct nutritional values. If you want to give him some water give it in between a feed x
