Help Please - Unsettled Baby

[krissie04]

My Son is nearly 7 weeks and from last Friday he has been unsettled in the sense of feeding time and not a happy little person. He will only say feed maybe half of his bottle and then its like he doesnt want it and will cry and then when i elevate to my shoulder will settle peacefully. I am seeing the ped. next thurs and my community nurse on tues but until then i am becoming really upset as i dont know what is wrong. We are using Nestle Nan 1HA Gold and a Pigeon (S) teat. Before this he was a content bub and had no problem and was advised by these things were excellent to have him on. He has changed his little sleep pattern from a 4 hour to a 3 hour. I thought maybe he was getting frustrated on the teats and tried the Tommee Tippee (1) AND Avent (1) and was too fast for him.If he does drink a full bottle it takes 30mins or so and i want to have some time with him but after his feed its like he is so tired from the sucking and just wants to go to sleep after i have burped and given his back a massage to get any wind up. The nurse did tell me last visit i should see he will be awake for about 1 and half hours now but with him being like this its not happening. Also as of yesterday i am giving him with every feed Infants Friend to help him. I just read in a book (First Year for dummies) and it sounds like he has Colic so not too sure. So any suggestions on what i can do or familiar experiences would be appreciated cause i dont want to be stressing about my little one.
