It is difficult at this stage but will develop over the coming weeks. It''s probably better to focus on not forming habits that will develop into a problem routine. For example don''t bathe your baby late at night and play with them in the bath. Bath time is for cleaning not fun, at this stage so make it swift and earlier in the day because your baby is likely to be stimulated by the bath and not settle to sleep straight after one. Not something you really want , the wrong side of midnight!!
