My baby has started to want to go to bed earlier. He used to go at 7.30, now its more like 6.30. This clashes with hubby getting home from work and dinner etc so not ideal as he takes a while to settle. He starts rubbing his eyes at about 5.30, should I put him down then or will he wake even earlier? He wakes 6.20ish. Hes 21 wks.
