I had one of them. He dropped all daytime naps from around 6 - 8mths, and woke every hour for 3.5yrs and was always awake by 5am.
On top of that he was left for the first 2.5yrs of his life suffering badly with asthma. He's nearly 21 now, and back then they said children under 7 couldn't get asthma, so didn't treat it... until we nearly ended up in hospital on a nebuliser, when finally they gave him pumps!
His Dad (now a distant ex) was useless, so i did it all on my own. She wants to try pacing the garden at 2am trying to help your baby breathe, or being up every hour with him screaming, and living in the real world!
