Ds (10 months) is under investigation for developmental delays. Physio said his head strength is not too bad, but he has intermittent muscle tone so sometimes has a tendency to slump.
He is nearly 10 kg, and his car seat only goes up to 9 kg, his head reaches the top. Our dds went into forward facing when this happened, but they were older and stronger. Bigger rear facing ones are so expensive, I wonder if anyone can recommend a good one so we don't waste our money.
