We're expecting #3 in January and am wondering how people go fitting 3 car seats in the second row of a CX9?

DS is in a SNS Hi Liner and with him needing to put the seat belt in himself every trip it might be a bit difficult with an infant seat in the centre. Also is it's possible to put him in the 3rd row in that seat by having a bolt added in the back?. He's a little too short to just sit in the back row without some elevation to stop the seat belt cutting across his face. Plus I'm scared to have him WAYYYY back there.

DD is in a SNS MaxiRider.

Having both a Hi Liner and a MaxiRider doesn't really leave much room in the centre seat. Never mind actually having to reach over and put a real baby in it!

So if you have fit 3 seats in the back row, let me know what you have and what works best for you, or if you think relegating DS (who will be 6 when baby comes along) would be best.

TIA
