So we attempted to have our son sleep in his crib..it worked for about 5 minutes..he was asleep..he'd cry, I'd check on him, he put his arms up to me..I'd pick him up, he'd lay on me and fall back asleep..we'd put him down and then after 5 minutes he'd start up..is anyone else going through this? I read on wonder weeks that at 5 weeks Babies to want more physical contact..could that be the reason?
