Hello, my DD has a mild speech delay and I can honestly say looking back it is probably the main reason we had such terrible terrible tantrums from 18 months - 3.5 years. Her comprehension was way ahead of her speech and it was most frustrating for her. If you have any doubts, please have her assessed ASAP as work now can prevent problems later. Also very important to get her hearing properly assessed by a pediatric audiologist.

Most states have public speechies but the waiting list can be quite long depending on where you are. We ended up seeing a private pediatric speechie who was just fantastic, because her delay was not considered severe enough to be considered for public treatment. We had qualms about the cost but it really didn't take a lot of sessions (maybe 7 or 8 each year over 2 years) plus lots of work at home to get it sorted out.

This type of language/auditory delay is hereditary so if you or DH have other family members who have had problems with speech or language then it makes it more likely. With our next child we will be doing the baby signing thing from an early age as I hope to get past any issues by providing another form of communication.

Please don't stress or worry about it ((hugs)), it's better to have her assessed and then you'll know if she needs a bit of extra help or whether her speech patterns fall into the range that is considered developmentally 'on time' for her age.
