I've got my Tripp Trapp highchair from when I was a wee one, and put it together the other day. Thought I'd see if my dS liked it so tried him in it a few times. He seems to absolutely love being up at the table with us and is generally much better being upright (he's v reflux-y), but my SIL came round yesterday and said babies shouldn't be in highchairs until 6 months.
Is that true or is she scare-mongering? Why would he not be able to sit in the highchair when his head control is great and he's happy in bouncy chair/bumbo/anything else really??
