Should I have a schedule for my 2 months? But how am I going to do it? He wakes up 1 or 2 hrs for milk. How can I make him sleep more at night? Or is he too young to start as he need his milk in the night.

Simple bed time routine is good to have. Don't expect child to sleep thru at night caz they are not biologically capable - stomach too small - will hungry. In the day try to put him to sleep every 2-3 hrs at least. There will be many growth spurts and teething episodes and sleep regression so u have to be realistic not to expect too much. At night got 3 hr is good - any more is bonus, 5 hrs is considered sleep thru the night le. Most will be able to at after 6 months when they start solids and have something more filling for dinner
