Does getting a good morning text from girl mean anything?

I have been talking to this girl for about a month and half now and we went on three dates which were awesome. Though she got out of a relationship due to her boyfriend cheated on her, and she isn't looking for anything serious just yet. Every mornng she sends me a good morning and occasionly I do to. Does this mean anything coming from a women, also should I send a goodnight text if I'm trying to be a challenge.

Also should I text her goodmorning once in a while, to show interest, or will it make me sound needy, I don't want to come off as needy.
