My ds is due to have his first set of jabs tomorrow, and I'm really worried that it's going to upset his system and send his sleep to pot. At the moment, although he doesn't nap much during the day (occasional big nap in moses basket or little naps in sling with me) he tends to sleep through from 7 till his 10 o'clock dream feed and then through till anywhere between 4 and 5 (and very occasionally nearer 6 ). Know I am currently very fortunate and that it will all change when he develops colic / starts teething etc, but am just wondering what others experiences were of these jabs and lo's sleep - and I guess health and wellbeing in general. Any thoughts?
