As far as nursery is concerned I will wait until baby arrives before deciding on a theme etc, as baby will be in our room until around 6 months as I'm hoping to BF & it makes BF much easier when you just have to reach over for baby as opposed to trekking into another room lol.
At the moment the theme of my daughters room is colourful animals, were renting at the moment so didn't have the freedom to redecorate. The walls of the room she is in are white so I bought vinyl stickers on Amazon, there is a big tree with multicoloured leaves, with owls & monkeys sitting on branches, at base of tree there is pink giraffe & purple&agreed tiger, other areas of the room have pink elephant, monkeys hanging from branches, more Owls, lions, pink zebras etc... & I also have little birds & butterflies flying over her cot. I got furniture from ikea, got white unit which fits those coloured boxes & placed different coloured boxes (pink, torquoise, orange) into the holes, so this is where little ones clothes are stored, I just wanted the room to be bright & cheerful. Little one can name all animals now & points & makes animal noises on her way to bed.
In relation to hospital bag will prob pack this around 34/35 weeks, last time out I ended up in hospital at 37 weeks (had to be blue lighted in without hospital bag or Hubbie) & had to send Hubbie to pick up hospital bag which had only been partially packed & was bit of a nightmare as I had no hair brush or dressing gown or tooth brush in there, so was constantly having to ask Hubbie to go & fetch things & he could never find them, so when I pack it this time, I'm going to pack it properly, nothing will be left out lol!
