Couple of issues going on with DS at the moment which I would welcome a little help with if you don't mind?
He's 17 weeks, EBF, independent sleeper at naps and BT. Since 14/15 weeks hit things have been a bit haywire, he's had a cold, got two teeth, learned to roll over and started tummy sleeping. Plus it's 'that age'

but we've had increased night wakings with some early morning cot parties, I treated initially as a growth spurt but it's been three weeks or so now and the wakings continue. He's not particularly hungry at the NWs either, will feed a bit and go back to sleep earlier in the night, but closer to 5am feeding doesn't get him back off.
Ali and Marta have kindly been helping me on the BF board but we've come to the conclusion it might be UT causing the problems. I hadn't really considered it but the problems did also coincide with returning from holiday and DS starting to nap better, especially in the afternoons (on holiday he just had a catnap or two as we were out).
Last two days: (just for info I'm not ideally aiming for a 'standard' EASY - a longer lunchtime nap with shorter ones either side works much better for us as a family, Tuesday was a bit odd because second nap was shorter).
