Sitting

Hi Guys -

So my little man is 6 months old and isn't sitting yet. I have two older sons who went at their own pace and I know it's normal to take their own time, but what are some things you guys did to encourage sitting up by themselves? I'm trying to help by holding him up sitting all the time but he just folds forward Everytime. Not much improvement over the weeks. Did you use a baby chair? Exercises?

Drop some tips! Just want to make sure I'm doing all I can as mom to help 😘

He's a big boy. 20lbs 3oz at his 6 me nth check-up yesterday and 28 inches long.
