Hey loopy - dont despare!!!! It gets easier honestly (says she with baby no.7 on the way) so you see its not all bad!!!! At 15 weeks i would try carrying on encouraging him to feed in the day and perhaps add a petit filous at supper time so he gets used to "day for play and eat and night for sleep" kinda routine (dont care what any midwife says, all of mine have been having a little solids by this age!) it works for me, or perhaps a little rusk or cereal last thing so that his tummy is full to go to bed on, it may take a few days but they normally get the message, you could also try (big one this one!!!) letting him cry at night for longer periods of time so again he gets used to attention in the day but nothing at night. Hope some of this has been of help to you, his clock is wired back-to-front is all and needs a bit of a shock to jolt him back to the right time zone!!! LOL heres hoping he settles down. Take care and make sure you are not getting frazzled too!!! xxx
