So I live in a basement suite with two rooms that are exactly next to each other. There is just one wall separating them. I have one of those Graco play pens in my room that my five month old usually sleeps in and her actual crib in the other room ( she hated the crib in her early days but is now seemingly favouring the crib more ) but recently I have been letting her nap in the other room on her own. Do you think it’s too early?? She cried for a bit ( like three minutes ) and then suddenly I heard no sound, when I went to check up on her, she had fallen asleep. Do you think it’s wrong at this age to allow her to cry a bit ?( max four minutes till I pick her up). She’s teething and can get super fussy sometimes.
