DD2 is 12 months old and weighs just over 8kgs - she's quite petite but also quite long. She's getting a bit too big for her rear facing baby carrier car seat and complains bitterly when I put her in it.
I've looked on the net for the car seat for the next stage and they all say suitable for babies that weigh 9kgs +, so she's still under that minimum despite being 3 months into the age range.
Would it be OK to put her in one anyway?
