I only started to feel baby kicks at ard 5-6 mths. Started out like bubbles, flutter, hard to distinguish but as the time progresses, gets stronger and frequent. Depends on how active ur baby is, mine I cld feel throughout the day, usually aft I eat, more pronounced while lying down. Baby hiccups will be like a rhythmic flutter, consistent movement, I cld only feel tt distinctly aft 7 mths.
