My baby has his 4 month vaccination last Thursday . The next to nights he was up a number of times in the night and would not settle. He's usually a really good sleeper and normally wakes up once for a feed and goes straight back to sleep . Since Thursday he has been right of him milk only taking a few ounces , he would usually drink 6-7 . He has managed to finish a few 6 onces but most the time he's only drinking a few . He also had a bad cough at the moment, I'm not sure if this is linked to the vaccine or just a general cough? Has anyone else experienced this after 4 month vaccination? He still has wet nappies and is still his happy self most the time unless he is tired . He seems to also be sleeping more during the day . Last night he did sleep pretty well but has hardly drank his bottle this morning . Any advice appreciated. Thank you
