Our son is 4 1/2 months - weighs 18 pounds (was 8,07 lbs at birth) and is exclusively breastfed.
He used to sleep through the night, but for the past 2 weeks, he wakes up crying between 2 and 3am. Paci, shh/pat won't work, he only falls alseep after being fed.
Should I introduce solids at this point or still wait until he is 6 months old?
