My 18 month old is a late bloomer. Late in crawling and walking. Whenever I talk to parents, it's as if my son is the only one that goes through every sleep regression- first three months were horrible; at 4 months, it lasted six weeks; at 6 months, three weeks; at 8 months, it lasted two and a half months; at one year, three weeks; then he had six weeks at 15 months and now at 18 months, he woke at 2.30am and refused to go back to sleep. I'm so angry right now. It's like he's always terrible. It always lasts the longest with him. It's the primary reason why I don't want anymore children. Is there something wrong with him? He's the one who goes through all of them, and lasts the longest. Why? Am i just a crap parent that should just go back to work and leave him in the care of others?
