hey
well mother choice and In good care car seats are crap I just got rid of one because it was just dangerous it was in my mothers car and I couldnt stand to have my daughter in it as it would not stay in position we ended up getting her a maxirider ahr as it was the closest to the meridian in my car car seats are worth every cent.
the cots from kmart don't seem to be very good on Friday a girl in my mothers group said to me she had to glue hers together as the bars keeps coming apart, but then I would not spend much on a cot as my daughter is 9 months old and she has probably spent 2 full nights in her cot as she usually ends up in my bed as she hates her cot but I think that is just her I got my cot from Toys r us and it was about 400 and it is sturdy and does a good job when my daughter will sleep in it.
even a second hand cot with a new mattress might be a better option the a kmart cot.
sorry have no idea about the target but kmart and target have the same owners so I would assume similar stock really pays to go in and have a look and remember babies kick the rails fairly hard.
