Hello Yankita, I went through this same ordeal when my daughter was between 6months and 18months (now 4). I basically weigh her every week. She was below the average weight for a long time. I was sick worried. However, she was active and eating enough to get her through the day. And of course she did not sleep well because the stomach is always half empty! Now everything feels like a distant memory, she eats very well, right weight for her age and sleeps through the night in her own room. This time will pass. As long as you are happy she is consuming enough for a given day. All the best.
