Pack it whenever your ready, I'm 29 weeks so I'll be starting to pack my bag next week as my babies have been born early so it's safer for me that way lol. You pack knickers, dressing gown, nighties or pjs, tops, pants, socks, bras, travel shampoo, conditioner, body wash/ soap, shaver, credit card or money, camera, phone, charger, slippers, hair dryer, hair ties, make up if needed, tissues, note pad, pen. I can't think of anything else off the top of my head lol.
