We started Pick Up Put Down 2 nights ago after reaching end if my tether as DS wasn't sleeping more than 2 hours a time and wanting to feed back to sleep each time and he was exhausted in the day.1st night went well, cried for "only" 30 mins and settled with less each time. He is 6 months and fully BF with dream feed at 11. But he ( and I) both picked up a cold on 2nd night and last night he was much more difficult to settle, due to blocked nose I think. He isn't unwell and is ok in himself but I am worried the aim of PUPD is to he him learn to sleep, not to think Mummy isn't cuddling him with his cold? DH thinks we need to continue or it will confuse him.
Any advice? Should I stop and try another time or persevere if it continues as just a cold?
