Development of my baby at four months // Life of Motherhood

Since my baby is four months old he is more active than before.
He now play alot by himself,he can't be left alone inside for long otherwise you will meet him in a funny position.
Someone that have not sit and he's getting ahead of himself to stand up, he was just learning to sit with the help of pillows and clothes yet he will be doing as if he can stand up.
Yesterday I was in the kitchen and I left him in the room laying down on is back until I heard his crying, I rushed inside thinking something have happened to him but when I saw him, I met him lying flat on his stomach, he has been turning around and got stuck, he was unable to control himself and started crying.
I don't know what to do I just stand there laughing at him and when he saw me laughing he started laughing too even though he didn't know the reason why I'm laughing.
He is now my laughing mate and gist partner because if he's not sleeping, I won't get bored, no time for brooding and no time for unnecessary thought.
It is this time I know the reason why they call babies bundle of becoming I now laugh a lot as he tries out his new personality.

Even though he makes me laugh when he is not sleeping and at the same time it is another round of work looking out for him not to injure himself.
His smile is my daily dose of happiness and I can't trade for anything.
