After reading everything I needed to know about having a new baby, I spent weeks religiously sticking to what "experts" advised we should do with our babies at each week and what milestones they should hit when and what age. Trying to force a routine, eating at specific times etc.
Fast forward to now and I feel incredibly guilty and a little sad that I spent so much time making sure my DD was hitting targets and stuff that maybe I didn't enjoy those early weeks as much as I could have! I now know she would put herself into a routine when she was ready, she would smile, laugh and coo when she was ready and just all round do things in her own time. As a new mum, I felt like all I had was the advice in books and articles and thought that was how I had to follow things.
It's true what they say, time goes so fast, and I really wish I had relaxed a little more and just enjoyed those weeks when she was small!
