If your baby can move on his own from his back to his tummy then if he rolls onto his tummy while sleeping you can leave him in that way. However, if he hasn't started doing this on his own he has to sleep on his back. In such a case you can give him assisted tummy time.
For any such things, you should ideally consult with your paediatrician so that they can assess the situation first hand.

If this has started recently it could indicate that he is going through a growth spurt. This is usually when children tend to be more fussy and cranky, mainly due to their hunger. During a growth spurt babies wake up often and wish to be fed consistently throughout the day.
A few things to check when your baby cries include; a wet nappy, hunger and just crying out for comfort.
Try feeding your baby every time he cries. Most often this helps to calm them down and put them back to sleep.
If you feel that there could be anything else that is concerning in your baby you need to consult with your paediatrician.

Sir, pl don't make a habit of making baby sleep on chest. Later on it will be difficult to change this habit.

Let the baby sleep in swing it self.

Hi friend.
Dear this is very natural cycle in babies. Most of babies sleep in day time and play in night time at the age of 4-5 months. Actually when babies live in mumma's womb at that time if you noticed we feel more movements in night time. So after birth babies routine become same as before birth till the age of 4-5 months. So don't worry dear. You will have to adjust just for 2-3 months.

Its good for her just make sure she is comfortable and dont let her sleep at one side for a long time. And always make her sleep on left side its very good for digestion.

Don't expect your baby to sleep overnight. She is small. She would require feed in 2-3 hours
