When do I switch to a big cot?

[OnMyJourney]

Hi, my baby girl is 4 months old and she sleeps in her next to me cot (tutti bambini cozee 100% recommend btw) she's only a small gal so she's got loads of room to spare but she now wiggles a lot and manages to spin herself around, like I'll place her one direction and I'll wake up she'll be sideways or done a 180 😂 she sleeps really well in her next to me cot, she sleeps through the night in it and I absolutely love having her next to me (I love her cheeky smiles in the morning 🥰) but as she's wiggling around so much does this mean it's time to consider getting a bigger cot sometime soon? I just want to make sure she continues to be safe and happy

I think if she's sleeping well she's fine would the big cot fit in your room? Because the recommendation is they stay with you at night until at least 6 months.

@Mt563 a bigger cot would fit in my room we only have a 1 bedroom flat as we're waiting to move so she will be our roomie for a while haha but yeah we could fit one in here, I just wasn't sure if I was supposed to swap it out when she started to move around a lot or when she can sit up
