Op just like MaryLou I remember it well. Sleep deprivation is total torture.
I did cc with all my 4.
It's called sleep training now as the fashion is to not mention letting children cry, as obviously they will be harmed for life!
,but it saved our lives/sanity and we had no choice with the younger ones as we couldn't allow then to keep disrupting the older ones sleep.
You are bloody entitled to a pity party.
You don't need to spend your money on a sleep consultant.
Put your baby in another room. In a safe cot, warm, fed, go in when he cries, sooth, go out. Don't feed or cuddle. Keep doing it. It may take 3 days or 3 weeks but it will work
We live In a society where, at the moment, the fashion is to be child led in everything regardless of the needs of the parents.
It's crap really as to keep babies/children safe it's vital that parents are well rested and functioning.
To your op it's a sensible parent who just goes with the flow.
