hi everyone, i'm new to this so please forgive any mistakes 
my dd is 25 months old and although she is speaking as such, i just feel in my gut that she has an issue with speech. the words she says are:
hello
hiya
bye bye
ta-ra
ball
cat
dog
gone
boo
yes
no
no way
oh oh (when she drops something)
night
there it is
there you are
oh wow....
there it is, there you are are not very clear words but you can understand perfectly what she is saying from the tone she uses. she used to say all gone but now only says gone.
she understands perfectly what i am saying, if i tell her to go get her shoes and put them on she will, if she is looking for something and i say "under the table" she will look under the table.
i have no worries with her on any other score at all, she can undress and is getting pretty good at dressing herself with a little help; she is very socialable and has a lot of little friends who we frequently visit and play with. she's also with a very experienced childminder 3 days a week when i am in work, along with two other children of similar ages so she is socialising pretty much every day, and i have discussed her speech with the childminder and she has told me not to worry and that she is doing ok, the same as everyone else.
i took her to the doctors last week to discuss my concerns but was told that she was on track and i really shouldn't worry.
if i ask her to point to any body part, she will, if i point to the body part and ask her what it is i'm greeted with silence. she gets her point across very well with gestures and her limited speech.
i know i have been told not to worry but something in my gut is telling me she has some sort of delay/issue with speech. i have watched her mouth when she is talking and i know it sounds daft but her tongue and her mouth just seem to make a funny shape when she is talking, and i'm wondering if she is just having trouble with putting her tongue in the right place if that makes sense?
sorry for the long explanation, all answers/advice gratefully received
