I also have the same experience with my baby. He is already 3 months old now, always wants to be carried even during breast feeding time.
It is really tiring. However, I read that the reason why babies want to be held a lot is because they crave for the security that our embrace offers. They feel safe when they are held close wherein they can hear your heartbeat and feel your warmth like when they were inside Mum's womb so parents like us will really have to bear the weight and take turns. 😂😂😂
And think that it will not last very long anyway. 😂😂😂
