Hello! 
Our baby girl is going to be 5 months by the time we spend the night at my aunts house over in San Diego in April for my husband and I's 5 year anniversary and I haven't the slightest clue where and what we should buy her to sleep in? 
I looked into the Snuggle Nest by Baby Delight but it says it's for 0-4 months old :/ 
I don't want her sleeping in our bed for fear of crushing her and 3's a crowd when it comes to the bed with my husband and I at night lol 
She normally sleeps in her bassinet at night or swing for small amount of hours during the day (her naps)
Thank you!
