It's in the middle on mine, the right hand one is for pre-wash. Conditioner goes in near the end, during the final rinse I think. You're not supposed to use it on towels though as it coats them to make them feel soft and that reduces the amount of water they can absorb. So they will feel soft but leave you damp.
Mine goes in the front at the left and goes in towards the end.
As bran said it does prevent absorbtion on towels as it coats the fibres making them sort of water resistant IYSWIM? Mind if baby isnt too wet maybe that isnt a problem? Normall the fist one is for prewash, the 2nd with a little drain on it is condiotner and the main big one is powder.
