We get giggles and have some for weeks but he’s never belly laughed. They all do it at their own pace x
My son was 13 weeks on Sunday and has only let out a little giggle once nothing since
My son is 13 weeks and he started a week ego😍 But, every baby is different, don't worry!
My daughter is 14 weeks tomorrow and I’ve only just properly noticed little giggles today - I wouldn’t worry at all!
