I'm a new mum to my beautiful DD who is now 15 weeks old! I've been to the drs 3x this week with her and am still worried! For the last week she has been having greeny runny poo which is not normal for her, being sick more than normal and tonight i have felt a pea sized lump on the back of her neck?? I'm insure if it's all connected and just a bug or something worse! I'm so worried I can't keep going back and forth to the doctors!
