My MIL came over today and criticized me that my 2 year old (29M) is still in a crib. My daughter hasn’t tried to climb out, doesn’t cry or anything when I place her to nap or at bedtime. But I feel awful is she too big for a crib at that age? I thought it was only when they start showing signs of hating the crib. My daughter shows no sign of wanting to get out. She’s preemie so her speech is delayed so I can’t ask her if she would like a big girl bed. Opinions? Is MIL right? Or is it ok until baby girl decides she’s ready for a big girl bed. Thanks.
