it is a developmental behavior for a baby to sleep thru at 3-4 months (lots of growth which needs sleep and lots of yummy mummy milk). Then at 4-6 months they have a growth spurt and start requiring milk feeds at night again, unitl your milk supply catches up, so this can be a week or 2 (or longer depending on your baby )

children and babies get the most beneficial sleep patterns between 8pm-midnight, deep and restful.

perhaps he is overtired and gets his second kick in...overstimulating him and therefore hard for you to settle him

plus as he is used to going to bed later, you would need to 'retrain' his bed time
start simply and without pressure on you or your baby

Here are some tips I give in my mother and baby classes

Identify what your baby?s tired signs are
Jerky movements, eye rubbing (in older babies), grimacing, crying, clenched fists. Once you have identified your baby?s tired signs, act on them and set about putting your baby to sleep. A tired baby can easily be distracted for a few minutes, until the tired signs reoccur. Distracting your baby when they first show tired signs will result in your baby becoming overtired and they will be harder to settle.

Learn your baby?s self settling signs
Soft staring, quiet stillness, soft face, relaxed breathing. Not all babies will exhibit obvious self settling signs. You may notice, however, a few minutes prior to your baby showing tired signs that he or she may become quiet or stare at an object.

Sleep promotes sleep
Allow your baby to sleep during the day. Overtired babies (and adults) find it hard to relax and unwind, releasing into sleep.

Be consistent with a bedtime routine
Create cues for sleep for the evening, such as bath, breast feed, bed, no play and quiet time, a quiet comforting cuddle, putting into PJ?s or sleeping bag. Babies thrive on consistency, as the pattern of the day gives them clues as to what is going to happen next, this in turn promotes feelings of safety and security for you baby.

Put your baby to bed relaxed and drowsy but awake
Which can help encourage to your baby to self soothe, and with development of sleep maturity (which is different for every baby), self settle to sleep.

Give your baby time to relax and unwind prior to sleep.
Just as we need to unwind after a days work, before relaxing and then drifting off to sleep, so do babies. Give your baby some quiet play or cuddle time before their sleep.


I hope this helps
