Sit up assisted around 5 months. Sat up by himself around 9 months old. Different baby have different development pace.
Mine sit assisted at 5 mth n sit up by himself at early 8 mth
Abt 5-6 months for sitting and abt 7-8 for by themselves while lying on bed. Every baby is different so no need to rush. If u are concerned then try to let baby have the opportunities to do the above
All bb achieves it at diff times, can use bumbo to assist them!
Mine about 5mths old.. but i agree, to each their own :)
