Hi Shantal.
Also don't think you have to be concerned but I for one love my sleep and when baby sleep all of us are just functioning better.
We did the sleep sense programme with GoodNight Baby.
www.goodnightbaby.co.za.
It is a very gentle approach to help and learn your baby to fall asleep on his own when he wakes up and not to rely on sleep props, for example the dummy.
It has changed our lives and my son, now 2.5 is sleeping like a log almost every night.
They do go through growth spurts and emotional development which do affect their sleep but if they have the know how they transition back to good sleep very fast.
Give it a go, what do you have to loose?
Good luck and keep us updated!
