Good day mums and docs, my son who is 11weeks today is finding it difficult to suck. This started immediately after the 10th week penta2 vaccine. He developed a little temperature in which I administered paracetamol according to the doctor and the temp is quite okay by the next day. His eating habbit reduced from that day (5/4/17) but got worst today. I 've forced him to suck since morning and he won't rather than crying. He smiles and sleeps well but I'm so confused with his eating habbit. This afternoon, I had to express breast milk to feed him with a spoon,he ate a little but I'm not still satisfied. What do I do next please?? URGENT ANSWERS NEEDED....HELP OOOO
