My DS is 6 weeks old and from newborn was very sicky, he is also as the title says a very grumpy baby, when hes awake he spends most of the time just crying (he still hasn't smiled either)He has also been very constipated since xmas and now has lactulose to help. At the 6 week check on friday I was given Infant Gaviscon for him as what I was describing sound like reflux. I have searched the internet for reasons and not getting anywhere. I have tried Infacol which didn't do anything as thought it could be colic, but he doesn't bring his legs up to his tummy or anything, he actually stretches them out when he cries. I have only noticed a slight difference in his sickyness since starting the Gaviscon but that is it. I'm at my wits end as all my attention is going on him and not my DD, and I feel helpless as I don't know whats wrong!!! Any advice much appreciated!!!
