I really thought that DS would sleep better once he started walking (that he would wear himself out & just crash!) - but it's not true! He is still a terrible sleeper!

He has a morning nap around 10am (40 mins), then an afternoon nap around 2 (2 x 40 min sleep cycles - but I have to resettle him in the middle). At night, he sleeps ok from 8pm - 11pm (ish), but after 11/12 he wakes up every couple of hours & we have to keep settling him (dummy & pats).

He used to be good at self-settling (I would just give him a dummy & walk out & he would grizzle then go to sleep within 10 mins). Now he cracks it if I leave the room before he falls asleep. Is this a developmental stage? Will he get used to going to sleep by himself again? Sometimes I wonder if that's why he seems unable to resettle himself over night?? It's so frustrating (and tiring!). We want to start TTC #2 mid this year - but I don't know how I would manage a 2nd one when the 1st one still can't go to sleep by himself & needs regular resettling overnight???
