No experience of this previously so just wondering whether it is common or possibly a cause for concern. 2.7 yo DS is pretty good with talking, good vocabulary for his age and can in most cases explain himself well. In the last few days he has started to stutter at the beginnings of sentences e.g "come-come-come-come on the slide, Mummy", "wha-wha-wha-wha-what's that" etc. It's worse when he's tired but seems to be happening more and more... Is this a phase that a lot of toddlers go through which then rights itself, or something I should keep a close eye/ear on? Grateful for any thoughts.
