Lo is just about 16 weeks old and has always slept well. First wake up in the night is usually between 5-8 hours after being put down then will wake about 2-3 hours after. When he wakes he cries but as soon as I pick him up is fine, he'll scream the house down if I need to change his nappy but other than that is pretty quiet. Anyway he had started waking much more frequently which I'm assuming is the sleep regression kicking in but he is waking up screaming and won't calm down when I pick him up only if I feed him. He is then sometimes taking ages to settle back to sleep, again something that would take minutes. Just wondered if this was also common in the sleep regression or if something else is may be going on and if anyone had any advice or experience of this? TIA
