My daughter mostly baby talks, soon to be 18 months... Normal?

yes its normal the good sign is she is saying words and joining some together, it doesnt matter so much how she says them at tthis stage because it will become clearer. my daughter was the same around that age, then all of a sudden around 2 her speech came on really well she started repeating anything and everything and it become really clear. she will get there just give her time and keep practicing.
