You would be surprised at how fast they grow!! And it won't matter what the Dr says, you'll be lifting and carrying whatever weight she is! Plus her baby carrier, her nappies, spare clothes, nappy change mat, wipes, powder etc etc etc.

Wait until you have the next one and are also trying to juggle a 2 year old who needs to be cuddled at the same time as the new baby.
