About my child

My child is 2 year old and his name is Gerardo. He is my joy and my desperation,my delight and my trouble. Because he doesn't sleep well,  I'm often very tired. He doesn't like to obey my rules and so I'm which makes me very stressed...but upon seeing his charming smile and big eyes I forget all my fatigues.
To have a child requires a lot of patience, much responsibility and little sleep...but to be mother is the most incredible,extraordinary and fascinating adventure I have ever done embarked upon.
Try to believe.

Regards

Excellent work! My correction are just suggestions on how I would have pharsed it. I am not an expert on grammar, but as a native English speaker, this is how I would have written it.

I hope you get some rest, it is hard being a mother to a toddler. I have 5 children and my least one is 7 years old. The time when they were toddlers went by so fast.
