Its about routine dear... if he is sleeping all day then how can he sleep in night... make him awake in day time. Engage him in activities.. take him out so that he won't sleep... you have to do this for few weeks then he ll adjust...

Hi give daliya at night as it causes Sense of fullness in the stomach and bring sound sleep to the baby and also give breastmilk at midnight for satisfying the baby

Dnt give phenargan... Not advisable at all.. He will sleep by end of 3rd month.. Find the reason of not sleeping.. Like his health is fine, or uncomfortable clothes, or lights on in the room, or weather too cold, or hungry, or colic pain or simply playful..

Baby is so small. It may be due to gastric issue. Rub hing mixed with luke warm water on the naval and move baby's legs in cycling position. You can use mamaerth digestion and colic relief easy tummy roll on made up of fennel oil and hing only. It is effective and easy to use and carry also. I have heard a lot about it. If all this do not helps you then go to your paediatrician.
