3 month old wants to sit whole time

my baby was sitting at 3 months and by 4 mnths was sitting with support and she also just wanted sit alot and at the time she was also crawling, very early. by 5 months was standing up with support and by 6 perfected taking steps along furniture. she just entered 7 mnths.

kids all different, you cant stop them. i was worried when mine was trying to stand at 5mnths but most people said you cant stop them.

they do things when they ready to. K head was firm from day one. always very strong

leave them to be

My baby boy is 3 and a half months and he wants to sit the whole time. He tries to pick his head and himself up straining forward if I lay him down. And starts crying if I don't let him sit.

Now I wanted to know if its bad if I let him sit up a lot, supported of course. Isn't he too young for that? His neck is quite firm.

He does have reflux so I wonder if that has something to do with it or is that just a normal developmental milestone?
