By the time we return back to London, my daughter will be 2.5 years old. We are debating whether to buy a toddler bed for her and give crib to baby brother (who will be 9 months at the time) or buy another crib for him. Her crib, you can take the side bar off and make it to a toddler bed as well...but not sure how long it can really be used. It is an ikea crib. Should we just buy a toddler bed for her? I am just worried about her climbing out of the bed and playing when she should be sleeping or roaming the house at night! But I figure, most dont use a crib past age 3 right?
