Feeling all emotional

How can my second baby suddenly be 18 months old?!... Though having recalculated this again she is actually 17 months old... Where did those baby days go? Those awful early days of new born hell... Well I had new born hell for 6 weeks with such a poorly baby until finally the hospital diagnosed her with Lactose Intollerance and I had to stop breast feeding and she went onto lactose free SMA milk... She was then like a different baby, like someone literally swapped my baby for a happy healthy one instead. Anyone else have new born hell that flashed past them in an instant? I wish I had treasured those early days more, but I had a bouncing fast toddler to also keep up with bless him so I had to share the love, second baby is so much harder!!! Here is my tiny little froglet as I nick named her...
