crib help please

Kaitlyn

okay so. we got a free crib but has a bunch but looks roughed up a little. half assembled no directions was givin to us live in a small two br. apartment this is 2nd child. she will be in the bassniet in our room for a while or has long as she can be. the full size crib fits in sons room but i dont think i want them sharing a room at all till she sleeps through the night an she may need to go in the crib before that. we couls fit a full size in our room i think just will be a tight squeeze. i had a mini crib for my son but we went into a shelter when he was a year i was thinking os it worth getting an other mini crib since not sure when moving or deal with the tight sqeeze an buy a full size crib an put it in our room?? i dont even see how to adjust the matress up high or anything. the people got it from don't have the directions either not sure what type of crib not in the best shape so we thinking of just buying a new one. question is buy a full size or mini crib?? looks like it qas damaged or beat up loads of scratches an marks on it
