I just bought ergo baby carrier, because she is the same. She can stay in a babybjorn chair for 10 min not more, basinet too. So I try my best during the day. Another one is pram she sleeps well in it, so if I feel overwhelmed with things need to be done, i try to make her to sleep in it 🫣
You need a sling and to lower expectations of getting stuff done :)
Deffo on the sling band wagon- worked for my first who was the same. That first cup of tea I made I still remember to this day, having the use of both hands!
Have you tried baby wearing?
