Blake rolled front to back 4 months to the day but hasn't rolled the other way yet. He also hates tummy time. He does those 360 spins and also likes to roll onto his side (usually to try and chew the cot bars). I'm really glad he doesn't do the other way, watching my Sis attempt to change my 10 month old niece's nappy is hilarious. She rolls everywhere, it goes everywhere, it's a battle to get the new nappy on etc. I'm going to relish this time when he doesn't move before it all goes crazy!
