Baby is too small... Dont self medicate...as baby is unable to sleep and uncomfortable bcoz of nose blockage...and chest congestion also there.... Dont wait and once consult doctor asap....

For 3 months baby what you are giving to eat ??

Upto six months breastfeeding only recommended...
After that only you can start giving semi-solid foods along with bm or fm...

As of now check once if baby is active,having feeding means ok...
If not do check with the Paediatrician once...

Don't give gripe water. At this age babies will wake up for breastfeeding again & again & will some babies sleep whole night.Consult with doctor if baby has colic pain also if u r using diapers check if diapers r full & need to b changed

Babies sleeping pattern will be changing...

Once they grows gradually they will have continuos sleep at night times...

Babies do wokeup at night for hunger,so jus feed your baby bm and make to sleep...

Now baby is jus 5 months old,they require day time sleep too...and as Srilu mentioned make sure that baby is not feeling discomfort...

There will b some reason for baby not sleeping in night like hunger, gas accumulated in stomach, baby not feeling comfortable in clothes, diapers r full & need to b changed, temperature of room, or if is sleeping in evening time , then sleep will reduce in night .First check what could b reason for baby not sleeping.

Don't give. Because of this spice baby will get motions.
Feed your breast milk stomach fully. Massage her body with oil and bath her evening also. It helps to baby sleep.
Observe she has any discomfort means any nose blockage. Don't sleep her directly under the fan or AC.

New born babies do like that at night. Some times baby feels insecure. So baby sleep after cover with blanket and put pillows both sides.
Don't sleep her under the fan . After feeding compulsory wait for burp.
Slowly she will adjust to environment .

Don't wry that's normal....if baby is happy n doing fine nothing to wry abt it...

Squeeze some bm half of little spoon and add a pinch of hing (asafoetida) in it... and apply it on baby's navel with clean cotton... It will help him to release gas. Another solution is.... Take 1 spoon luke warm water and add a pinch of black salf and same amount of hing and give it to baby.... These both remedies are safe for releasing gas in babies..... U can try one of these ideas...

This pillow is fine... But keep changing position of baby like if sleeping in right side then after an hour turn left side...like that. Don't make him sleep in one position for long time...
