In laws purchased a car seat a few weeks ago for when they have DC who is 9 month old and almost 9kg. I remember discussing rear facing being safer a while ago. I don’t remember if I fully looked at the detailed specs when they mentioned they wanted to get this one. I’ve been looking today for a new seat for our car and I’ve looked at the one they bought in full detail and realised that it is only rear facing till the child reaches 10kg before it must be used as forward facing. I’m kicking myself for not fully reading all the details when they discussed getting it. I’m not too happy that DC will soon need to be forward facing. Should I say something? They may have 3 or so days before it will hit the 28 days after purchase so may have time to return it. Issue is they can be sensitive and I know DH will think the one they have is fine so it could cause an argument. What would you do? They will only have DC once a week
