The Big Move

My little girls is nearly 3 months and I feel like she is getting big enough to move into her cot but I'm just not ready to be apart from her.. I'm a first time mum so I'm new to this... She is an amazing sleeper and I know she will sleep anywhere but it's me that's having the hard time.. The thought of not having her in the bassinet next to me breaks my heart.. I can't deal!! What age did you all move or plan to move your LO into the cot? And have you or will you move them into their own room?
