She’s 4 months next week. She’s becoming a bit too big for her next to me and is starting to wanting to roll over so she’s almost face planting the sides of the next to me. Google says 4-6 months but I always just thought 6. Is it too early or should I go ahead and put her in a cot ? I wouldn’t want to put her into a cot to sleep if it was unsafe. (Ofcourse I know her starting to put grow the next to me can be too) 🫣
