so I think LO has been having a growth spurt. For the last 3 days he's been feeding every 2 hours during the day, really guzzling and waking up crying for milky, and the other night it was during the night too. One day he'll sleep all day, then the next hardly at all. And now his wee seems to smell much more? Llike as soon as he's peed I can smell his nappy? Perhaps this is because he's drinking / peeing more? Or could it be an infection!? what do you think?
