Dear Parent, Give me details about her feeding/ urine and stool/ general well being. Usually while feeding baby will suck some amount of air into her stomach and that will produce gas trouble. You should do burp post feeding for about 10-15 mins. Check for other causes like tight clothes/urine and stool passed/skin rashes/insects/ears ..... Most imp reason is baby may be Hungry and asking for more milk during night... As if baby takes 10-15 mins continuos feeding, post feeding takes 1-2 hr sound sleep/ passes urine atleast 6-8 times a day/ playful while awake than you will come to know that she is satisfied...
