dear Supriya, I will advise you not to keep an ideal weight in mind but to jus  try to increse your baby weight .as every baby has his own growth pace . when the baby gets 5.4 kg weight he can.manage to sleep well at night , but this is jus an estimate . a steady weight gain will be most beneficial.than.jus a number. try to fed the baby well through out the day fed every 2 and half hr and make sure they nap consistently.as.this will help in.weight gain .

dear Supriya, thanku for mentioning baby weight , now I can understand better. normally a 3 month old will not have any day/night confusion as babies get older during this time but in your special case ur babies are slightly underweight , your babies are still in tiny baby phase where they can have day/night confusion. For sleep age is not as important as babies weight as this shows growth .try to help them gain weight as this will help them stay awake longer during day and sleep more during night. Also make sure the naps and feds are in order like a.routine , this helps in increasing weight and growth.
