My baby boy has recently been quite irritable during the day and up until now, I have put it down to hunger / tiredness, however, he was sitting on my this morning and suddenly latched on to my finger and really started chewing on it (previously he would just suck). Does anyone know if this is a sign of teething or if it's just another thing he has learnt to do? I also tried rubbing his gums earlier when he was crying and he did stop crying. He has been putting everything into his mouth, however, I thought this was normal for a baby of his age (4 months). Does teething keep babies awake at night because he is still sleeping through from 8pm to 6.30am?
Thanks in advance!
