Hi hope someone can offer some advice or support. First time mum to an almost 5 month old. He got his 4 month vaccinations almost 2 weeks ago and has been more irritable in general ever since. It's like they have changed my baby from a happy smiley playful one to one that cries or is unhappy most of the time.i thought it was teething, which I think he is going through, but even with Nurofen and other teething remedies, he is still not himself really and I can't help but think it's the vaccinations causing the irritability. Can it last this long? His temperature is fine and has a good appetite,also he is sleeping well. But just doesn't want to play on his playgym as much and is generally just more whiney than he ever was. It's so upsetting. Nothing really pleases him. Unfortunately i dont feel i can approach my HV or GP as find them useless but I'm going to have to do something if this keeps up. Could he have had some reaction to the vaccines that we cant see? He isn't going through a leap as just came out of leap 4 when he got the jabs.has anyone else experienced this with their little one?x
