My son will be 2.5 by the time I deliver my daughter. He is still in his crib and seems to be content. He climbed out once in February and that's it so far. We have a bassinet for her to use until she's too big for it and I had planned on buying a second crib, since our son is still in his. Now I am second guessing myself. Our son's crib turns into a toddler bed, then a headboard and footboard for a full. We have a full size bed ready for him when he is ready. He is a good sleeper at nap time and bed time, so I would hate to rock the boat with switching beds, especially with about 5 weeks to go. From what I gather, most people move their older child to a big bed because they need the crib for the next child, but I'd rather spend the $ on a new crib so my son continues to sleep well. Hopefully then he will continue his naps too after the baby is born....?? He can fall asleep in a big bed at night with me laying beside him, but I've always moved him to his crib, because we don't have safety rails on the sides.
