15week old baby crying constantly

[clarejackjames]

Advice needed please. My 15 week old had his injections last week they was his 12 week ones as we was on holiday when they was due. They have really unsettled him, he was really chilled out before. He now crys all day and now unsettled in the night. I've tired everything you can think of. He's just so unhappy, he was abit poorly after the injections green pooh. He's bottle fed he's not really feeding today
