Baby wearing - that was my answer to every temper tantrum. My daughter is 6 now and I still find the easiest way to stop her temper tantrum is to engulf her in a tight hug for a few mins first and then ask her to explain to me what’s going on. There’s something magical about the human touch.
For myself as a daddy, whenever i take care of my baby girl from birth till now about 6months.. I learnt the more calm i am, controlling my inner self, my heart beat & my breathing to slow down… some how, my little one turn calmer. Hope this helps a little.
May be u try to carry the same posture as them. Sometimes the way we carry different and baby is already familiar with whoever carry him longer
It will take time.. have more bonding sessions.. let yr mum handle him lesser..
Don’t worry too much mummy. It will get better
