morning with balloons

My daughter loves balloons. Therefore (try to use more linking words) And we (try to be more precise, in this situation a reader does not know who WE are, so try to say e.g. my friend and I)my friend and I decided to give organize her a morning with balloons. In the evening we blew  inflated all of the balloons while she was sleeping slept. At 6 a.m. the next day they (again it's not clear who THEY are)my friends threw the balloons (not the balls, spelling mistake) around the room. At 6.30 she my daughter (in this situation it's more clear who you are talking about) woke up and joy started screaming with excitement. How It is wonderful when children are happy.

Very good job! Please try to be more precise while telling a story: use names like Luke, Sarah or my daughter/ mother instead of using we, they, she most of the time.

It is correct to use forms like we, she, he only in the following sentences when the subject is still the same. 

For example: It is my girlfriend's birthday tomorrow. She (you know it's THE GIRLFRIEND) will celebrate it with her family. 

Morning with balloons

My daughter loves balloons, so we decided to give her a morning with balloons. The evening before, I inflated all of the balloons while she slept. The next morning at 6 a.m. they  I threw the balls around the room. At 6.30, she woke up and joy started screaming with joy. How wonderful it is when children are happy.
